Figure 1
TracVision G8 System Diagram
Satellite Compatibility
The TracVision G8 is fully compatible with Digital Video Broadcasting (DVB
®
) satellites, as well as DIRECTV®‘s Digital
Satellite Service (DSS) satellites.
In-motion Tracking
The TracVision G8 uses a state-of-the-art actively stabilized antenna system. The antenna’s built-in global positioning system (GPS) allows the system to calculate the precise direction to the satellite from your vessel’s current location, ensuring the shortest possible satellite acquisition time. Once the satellite is acquired, the antenna gyros continuously measure the motion of your vessel and send commands to the antenna motors to keep the antenna pointed at the satellite at all times.
TracVision G8 systems equipped with linear quad LNBs (used in Mexico and Europe) can be connected to four receivers using four RF cables.

TracVision G8 Owner’s Manual - Guide to Operation
Satellite Library
Your TracVision G8 includes a pre-programmed library of TV satellites from around the world. If the satellite service you wish to receive is not already in the satellite library, an authorized technician can add two additional satellites of your choice to the library.
System Components
Your TracVision G8 system includes the following components:
Antenna Unit
The antenna unit houses the antenna positioning mechanism, low noise block converter (LNB), GPS, and three-axis sensor within a molded ABS radome. Systems equipped with a linear quad LNB (used in Europe, Australia, and Mexico) include a skew control mechanism that automatically adjusts the LNB’s skew to account for regional changes and different satellite services. Power, signal, and control cabling from belowdecks units are connected to the antenna at the rear of the baseplate.
Master Control Unit (MCU)
The MCU is the user interface, providing access to the system and its functions through an LCD and three buttons. The MCU also serves as the system’s junction box, allowing the system to use ship’s power and supply and receive data to/from the TracVision G8. The MCU can accept any power input between 9 and 36 volts DC; its power supply provides power to the antenna and galvanically isolates the TracVision G8 system.
Satellite TV Receiver (IRD) – Sold Separately
The receiver (purchased separately) receives satellite signals from the antenna unit for signal processing and channel selection, and sends the signals to the TV set for viewing. Please refer to the user’s manual provided with your selected receiver for complete operating instructions.
Guide to Operation

2 Receiving Satellite Signals
For TracVision G8 to receive satellite TV signals, the antenna must have a clear line of sight to the satellite. If you only receive intermittent signals or the antenna cannot find the satellite, check around your vessel for any objects that could be blocking the signal, such as other vessels, trees, buildings, other onboard equipment, etc.
Figure 2
Satellite Blockage
You must also be located within the selected satellite’s coverage area in order to receive its signal. Refer to your satellite television service manual to check the viable coverage area. For your
convenience, KVH provides links to several web sites that offer satellite coverage information. Simply go to our web site at: www.kvh.com/ footprint.

TracVision G8 Owner’s Manual - Guide to Operation
The satellite configuration on your receiver must match the satellite setting on the TracVision G8 system.
Satellite A on the TracVision G8 must be the same satellite as receiver Alternative 1 (or A, based on your receiver) and must be assigned the receiver DiSEqC 1 setting.*
Satellite B on the TracVision G8 must be the same satellite as receiver Alternative 2 (or B, based on your receiver) and must be assigned the receiver DiSEqC 2 setting.*
Refer to your receiver user manual for complete instructions for your receiver.
*DiSEqC settings only apply to European systems and DIRECTV DSS Plus
receivers.
3 Turning On the System
To use the TracVision G8 system, follow the steps below. To minimize the time it takes the antenna to acquire the satellite, do not change the channel during this process.
1. Turn on the receiver and the television. (Refer to your
receiver user’s manual for complete operating instructions for the receiver.)
2. Apply power to the TracVision G8 antenna.
3. Minimize turning the vessel for two minutes after turning on the antenna to allow the antenna gyros to initialize properly.
4 Changing Channels and
Switching to the Second Satellite
TracVision G8 can have a pair of satellites installed, either one of which can be the active satellite selection. There are several methods of selecting whether your TracVision G8 will track Satellite A or Satellite B based upon your location, type of install, receiver, and selected satellite service.
Europe and Australia
If you are not using a multiswitch, switching from one satellite to the other is as easy as changing the channel using the receiver’s remote control. TracVision G8 will automatically switch between the two satellites as necessary to receive your selected channel. If you are using a multiswitch, however, you will need to use the MCU switching option described in “Switching Satellites Using the MCU” on page 7.
North America
DIRECTV Subscribers
DIRECTV subscribers in certain regions of the United States will require a DSS Plus
receiver to receive broadcasts from multiple satellites. If connected to the antenna’s RF1 connector, the DSS Plus receiver allows you to switch channels using the receiver’s remote control. If you are a DIRECTV subscriber, but do not have a DSS Plus receiver, or you are using a multiswitch, use the MCU switching option described in “Switching Satellites Using the
MCU” on page 7.
Guide to Operation
54-0198
7
DISH Network™ (EchoStar) and ExpressVu Satellite Subscribers
DISH Network and ExpressVu subscribers will need to use the MCU switching option, as described in “Switching Satellites Using
the MCU.”
Latin America
In Latin America, including Mexico, satellite switching is unnecessary because programming is broadcast from a single satellite.
Switching Satellites Using the MCU
If you’re unable to switch between satellites using the receiver’s remote control, use the MCU front panel buttons to select between Satellite A and Satellite B. Press the left button to select Satellite A and the right button to select Satellite B.
Figure 3
Switching Satellites Using the MCU
Europe only:
Using the MCU to switch between satellites disables the system’s DiSEqC monitoring. You will not be able to use the receiver/remote to switch between satellites unless the system is restarted.

5 Watching Television
TracVision G8 will receive satellite TV signals whether your vessel is in motion or at rest.
Cable Unwrap
If your vessel makes several consecutive circles in the same direction, the antenna will rotate 720° before reaching the end of its internal cable. If it does so, the system automatically unwraps the cable by quickly rotating the dish in the opposite direction. During this time, your TV picture will freeze momentarily.
Fine-Tuning
You might hear slight mechanical sounds from the antenna, as the antenna moves continually in a circular motion to sweep across the satellite’s peak signal. The signal strength is then fed back to the control circuits to keep pointed in the direction of the strongest signal.
Sleep Mode
When the vessel has come to a stop and holds its position for one minute (e.g., at a dock), the antenna enters Sleep Mode, which locks the antenna in place to conserve power. As soon as the vessel moves beyond a 1° - 2° window, or the RF level changes significantly, Sleep Mode automatically turns off and the system begins tracking the satellite again (or enters Search mode to find the satellite).
If you prefer, you may disable the Sleep Mode function. Refer to
“Turning Sleep Mode On/Off” on page 69
for details.

2.1 Planning the Installation
Who Should Install the TracVision G8?
KVH recommends that a KVH-authorized technician install the TracVision G8 system. Installers should have experience installing electronic equipment on a vessel.
Materials and Equipment Required for Installation
Before you begin installing the TracVision G8 system, you need to verify that you have all of the following tools and materials:
Electric drill and
1
2" (13 mm) drill bit
17 mm socket wrench and
9
16" open-end wrench
Flat head and Phillips screwdrivers
Light hammer; center punch; tape; scriber/pencil
Wire strippers
A PC with KVH Flash Update Wizard or Windows
HyperTerminal installed
Quick-tripping circuit breaker or fuse rated for 15 amps
RG-11 or RG-6 cable(s) with F-type connectors (refer to
Table 2-1 to determine the number of RF cables needed)
Table 2-1
Number of RF Cables to Connect to the Antenna
Connecting to: # RF Cables
System with Circular Dual LNB
One receiver 1
Two receivers 2
Two or more receivers 2*
System with Linear Quad LNB
One receiver 1
Two receivers 2
Three receivers 3
Four receivers 4
More than four receivers 4*
* Multiswitch required. Follow manufacturer’s guidelines.
RG-11 or RG-6 cable with F-type connectors is required for all RF wiring. Use of any other cable will result in degraded performance. Use RG-6 cable for distances up to 75 ft (23 m); use RG-11 cable for distances greater than 75 ft (23 m). The KVH warranty does not cover degraded performance due to improper wiring.
You may want to connect four RF cables to the antenna in all cases. That way, if a receiver is added (or the system is converted from North American to European use) in the future, no additional RF cables will need to be run.
Plan the entire installation before proceeding! Take into account antenna unit placement, cable running distances between units, and accessibility to the equipment after installation.
If you are prewiring the system, be sure to route the N-type connector end of the data/power cable to the antenna location and the F-type connector end to the belowdecks MCU (see Figure 2-7 on page 28).

Choosing Component Locations
When choosing component locations, first keep in mind accessibility and cable lengths between units. For example, since the data/power cable is 100 ft (30 m) long, the MCU must be located within 100 ft (30 m) of the antenna. The major considerations in locating system components are noted below.
Choosing the Best Location for the TracVision Antenna
There are several factors to consider when choosing the location for the TracVision antenna.
Since the TracVision antenna requires a clear view of the sky to receive satellite signals, the ideal antenna site has an unobstructed view of the horizon/satellite all around. The less blockage, the better the system performs.
Keep the antenna clear of any obstructions above decks. The antenna requires a -15º to +85º look angle to receive satellite signals.

Blocked!
TracVision Antenna
Vessel Platform
To minimize tracking errors, place the antenna unit as close as possible to the intersection of the vessel’s fore­and-aft centerline and midships. In addition, do not mount the antenna too high off the water (limit height above the waterline to less than half the vessel length).
The mounting surface should be flat and strong enough to
carry the complete assembly (85 lbs/ 38.6 kg). To prevent warpage to the antenna baseplate, make sure that the mounting surface is rigid so that it cannot flex when the vessel vibrates. If necessary, add a strength member to the mounting site to stiffen it.
Be sure to account for the height and base dimensions (see Figure 2-2 on the following page). Also be sure to leave enough space outside the access hatch to allow a technician to remove the hatch screws and perform maintenance through the hatch.
Maintain at least four feet (1.3 m) separation between the
antenna and any magnetized materials, large ferrous masses, cranes, engines, derricks, other antennas, cables carrying high amperage direct current, or battery banks. Take extra care when mounting the antenna on a steel vessel; use an aluminum, brass, plastic, or wood (NOT steel or iron) platform to position the antenna at least four feet (1.2 m) above and six feet (1.8 m) away from the steel surface.
Be alert for devices that change their magnetic
characteristics when in use, such as CRTs (computer and TV screens), radar magnetrons, electric winches, loudspeakers, windshield wipers, and other devices with DC motors. The antenna’s internal sensor cannot compensate for changing magnetic fields created by these devices.
Radar Concerns
The TracVision antenna must be kept out of line with nearby radars, as their energy levels (from both the main beam and its side lobes) may overload the antenna’s front-end circuits. In an ideal installation, the antenna is mounted four feet (1.2 m) above and four feet (1.2 m) away from the radar (measured from the center of the antenna dome to the center of the radar).
The best placement for the TracVision antenna is above the radar. However, if there will be a significant horizontal separation between the radar and TracVision dome (i.e., at least 8 to 10 feet (2.4 to 3 meters)), the TracVision antenna can be placed below the radar as there will be little chance of signal blockage.

Antenna Unit Dimensions
Choosing the Best Location for the MCU
The MCU should be mounted in a dry location, allowing enough room at the back for connecting system cables. Also be sure to mount the MCU in a well-ventilated area to prevent overheating, which will damage the system.
The MCU should be placed so that the LCD display is visible and the buttons are accessible to the user.
The MCU is not susceptible to magnetic interference and does not need to be mounted on a level surface.

The radome exterior is treated with a special finish selected for compatibility with the dome material and transparency to the satellite signals. Application of additional paints or finishes WILL degrade performance, potentially beyond acceptable limits.
A full-size template of the baseplate mounting holes has been provided at the back of this manual.
Four small holes have been drilled into the bottom of the baseplate to ensure that any moisture that enters the antenna unit is able to drain. Be sure these drain holes do not become blocked.

3. Drill the four 1⁄2" (13 mm) bolt holes following the layout
in Step 2.
4. If mounting the antenna on a deck:
Mark a location aft of the antenna for the cable access hole. The hole must be large enough to accommodate the data/power cable and all required RF cables (see Table 2-1 on page 21 to determine the number of RF cables required). Cut out the access hole and smooth the edges of the hole to protect the cables.
5. Remove the antenna unit from its shipping carton.

17. Reinstall the radome. Secure in place with the eight screws you removed in Step 6. Install a protective plastic screw cap from the kitpack over each screw.
2.3 Connecting the Receiver(s)
Connecting the RF Cable(s)
Each RF cable must be an RG-11 (75 ohms) or RG-6 (75 ohms) cable fitted with F-type connectors. The RF cables should already be connected to the antenna baseplate (see Step 11 of Section 2.2, “Mounting the TracVision Antenna,” on page 29). The following sections explain how to connect the RF cable(s) to your satellite TV receiver(s).
To connect the TracVision antenna to your receiver(s), choose one of the following configurations (based on the number of receivers you will connect to the antenna):
Option 1 - Connecting One Receiver
Option 2 - Connecting Two Receivers
Option 3 - Connecting Three or More Receivers
Option 1 - Connecting One Receiver
One end of the RF cable should already be connected to the RF1 plug on the TracVision antenna. Connect the other end of the RF1 cable to the receiver plug labeled “LNB,” “ANT/SAT,” or “SATELLITE IN.”
Option 2 - Connecting Two Receivers
Two RF cables should already be connected to the RF1 and RF2 plugs on the TracVision antenna. Connect the other ends of these RF cables to the plug labeled “LNB,” “ANT/SAT,” or “SATELLITE IN” on both receivers.
The receiver that is connected to the RF1 cable controls which satellite the antenna is tracking. This is the master receiver. The receiver connected to RF2 can select different channels on that satellite but not change the satellite selection itself.
Installation
54-0198
31
Before you connect an RF cable to a receiver, turn on the receiver and TV and verify that there is no AC voltage present on the receiver’s input connector, measured between center conductor and shield. If AC voltage is present on the connector, DO NOT connect the RF cable until you have corrected the problem. This is a potentially dangerous condition that will damage the antenna’s electronics.
Option 3 - Connecting Three or More Receivers
(System Equipped with Circular Dual LNB)
To connect three or four receivers to the TracVision antenna, you will need to install an active multiswitch (Channel Master model 6214IFD or equivalent) between the antenna and the receivers. Two RF cables should already be connected to the RF1 and RF2 plugs on the TracVision antenna. Figure 2-13 shows a typical wiring arrangement for three or four receivers. Mount the multiswitch unit in accordance with the manufacturer’s instruction sheet.
Figure 2-13
Single Multiswitch Installation (Circular Dual LNB
System)
1. Connect the RF cable labeled "RF1" to the multiswitch input labeled "LNB RHCP +13V.”
2. Connect the RF cable labeled “RF2” to the multiswitch input labeled "LNB LHCP +18V.”
3. Connect the multiswitch outputs to individual receiver inputs. Use RG-11 or RG-6 cable with F-type connectors for all RF connections. Terminate all unused output connectors with 75 ohm DC blocks (Channel Master #7184, Radio Shack #15-1259 or equivalent).
54-0198
32
TracVision G8 Owner’s Manual - Guide to Technical Information
The use of an active multiswitch will interfere with the 22 KHz tone sent by DIRECTV DSS Plus™receivers to the antenna. As a result, the antenna will not receive the signal to change satellites when you change channels using your DIRECTV DSS Plus remote.

Option 3 - Connecting Three or More Receivers
(System Equipped with a Linear Quad LNB)
Systems equipped with a linear quad LNB have four RF outputs that can be connected to individual receivers.
Connecting Three or Four Receivers
To connect a third receiver, a third RF cable should already be connected to the RF3 plug on the TracVision antenna. Connect the other end of the RF3 cable to the plug labeled “LNB,” “ANT/SAT,” or “SATELLITE IN” on the third receiver. To connect a fourth receiver, use the fourth RF cable, which should already be connected to the RF4 plug on the antenna.
Connecting More than Four Receivers
To connect more than four receivers, you will need to install an active multiswitch that generates a 22 KHz tone (for example, Spaun models 5602NF or 5802NF). Connect the multiswitch unit in accordance with the manufacturer’s instructions. Figure 2-15 shows an example of a European multiswitch configuration.

Connecting Vessel Power and the MCU Ground Wire
Short circuits may result in severe electrical shock or burns. Turn off vessel power and test the circuit to ensure that no power is present before connecting any power cables. Do NOT reapply
power until all system wiring is completed.
The TracVision G8 system requires a 9-36 VDC power input. Since it does not have a dedicated power control (ON/OFF switch), a quick-tripping circuit breaker or fuse should be installed between vessel power and the MCU. Circuit overload protection should be rated for 15 amperes. For recommended power cable specifications, refer to Table 2-2 on page 22.
A power connector plug has been supplied in the kitpack to make connecting power to the MCU a snap. To connect vessel power and the ground wires, follow the steps below.
1. A large ferrite coil is supplied in the kitpack to help reduce conducted emissions from the vessel power cable. This ferrite coil needs to be installed for the system to comply with CE standards. To install the ferrite coil, make two loops in the vessel power cable and clamp the ferrite coil around the loops (see Figure 2-17). The cable, with both positive and negative wires, must pass through the ferrite coil three times to be effective.

2.6 Activating/Programming the Receiver
Before it can be used, your satellite TV receiver must be activated and/or programmed, as described below.
DIRECTV Activation
KVH makes it easy to activate a DIRECTV receiver. Just call KVH at 1-888-584-4163 and select the TracVision Product Activation Department (Monday - Friday, 8:30 a.m. - 5:00 p.m. EST).
DISH Network Activation
To activate a DISH Network receiver, please call DISH Network directly at 1-800-333-DISH (3474).
Other Receiver Activations
Please refer to the user manual that accompanied your receiver for activation instructions.
Programming European or Australian Receivers
Before the TracVision G8 system can be used in Europe or Australia, the receiver must be programmed to receive signals from the selected DVB satellite services. Programming is conducted using menu selections displayed on the TV screen. Please refer to your receiver owner’s manual for specific instructions.
Table 2-4 provides some key data for use when programming the receiver.

It is also important that the receiver’s settings for Antenna Alternatives 1 and 2 match the MCU’s installed satellite settings as follows:
Antenna Alternative 1 = Satellite A
Antenna Alternative 2 = Satellite B
Section 2.7, “Installing Satellites Using the MCU,” on page 42
provides details on the satellite installation process.
Programming DSS Plus receivers
If you are using multiple DSS Plus receivers and intend to shift from one satellite to another, only one of the receivers can be configured as a two-satellite receiver. All other receivers must be configured as one-satellite receivers. The two-satellite receiver will determine which satellite the antenna is tracking while the other receivers can watch any channels available via that satellite. Refer to your receiver owner’s manual for complete details on this process.
If you use an active multiswitch to connect three or more receivers, the multiswitch will interfere with the 22 KHz tone sent by DIRECTV DSS Plus™receivers to the antenna. As a result, the antenna will not receive the signal to change satellites when you change channels using your DIRECTV DSS Plus remote. You will need to use the MCU buttons to change satellites.

3. Apply power to the TracVision G8 system and allow the system to complete full initialization. Data should be scrolling on the PC display to identify any system problems detected. If no data appears, recheck your connections and setup.
4. After completing the review of the startup and operational routines, turn on the receiver and television and check the channels on the selected satellites. For linear quad LNB systems, check both horizontally and vertically polarized channels, if possible.
5. When all checks are completed, shut down the system.
Checking the Calibration Score
Once the vessel is moving, the TracVision G8’s internal sensor calibrates itself automatically to compensate for minor magnetic distortions. Since a well-calibrated sensor is important to maintain system performance, the “calibration score” should be checked the first time the vessel is underway. See “Viewing the Calibration Score” on page 79 for details.
A sample startup sequence has been provided in
Appendix C on
page 127
with the typical ranges and responses for the TracVision G8 during startup and operation.
Be sure to register the system for product warranty validation. When you register, you’ll also be added to our customer contact list, which will be used only to notify you of any product updates. Please refer to the Product Registration Form or visit www.kvh.com/register.

Updating Satellite Frequency Data
If the antenna is unable to find a satellite, the satellite’s frequency data may have changed. The Satellite Frequency Scan feature allows you to update the frequency data of any satellite stored in the system’s library.
This function should not be used unless directed by KVH Technical Support or a KVH-authorized technician.
With the desired satellite, band, and polarization selected, the system will automatically search for the frequency with the strongest signal. The system will then update that satellite’s programmed data with the new frequency (and associated network ID) and store it in the satellite library.
To update the satellite frequency data, follow the steps below:
1. Place your receiver in the satellite signal meter mode.
2. Select the desired satellite on the MCU. Ensure the TV
signal meter indicates that you have a strong signal.
If the antenna is unable to find the selected satellite automatically, you can manually point the antenna (see “Manually Controlling the Antenna” on page 68).
3. Select the desired polarization and band on the receiver.
4. Do not move the vessel. Your boat must remain motionless during the entire Satellite Frequency Scan process.
5. Follow the MCU menus on the next page. The scan itself will take a couple of minutes. Once complete, restart the antenna and ensure the antenna will track the new frequency.

Control Compass Mode
The Control Compass function allows you to turn autocalibration on/off, read the calibration score, and clear the calibration.
Figure 3-21
Control Compass Mode Menu Sequence
Selecting Autocalibration
Every antenna’s internal sensor module is calibrated at the factory in a perfect-world environment. However, hard and soft iron effects on your vessel can distort the local magnetic field, causing errors in the reported heading. These errors are minimized by mounting the antenna in a suitable location and are further removed by the system’s autocalibration feature, which compensates for minor magnetic distortions while your vessel is moving. The more the vessel moves with autocalibration turned on, the more accurate the sensor will become.
The factory default setting for Autocalibration is ON.
Figure 3-22

TracVision G8 Owner’s Manual - Guide to Technical Information
4.2 Causes and Remedies for
Common Operational Issues
There are a number of common issues that can affect the performance of the TracVision G8. The following sections address these issues and potential solutions.
Power Disturbance, Blown Fuse, or Low Power
Power Disturbance
If the MCU detects a short in the output to the antenna, the MCU’s resettable fuse trips. If this occurs, remove the short then wait one minute for the fuse to reset. If the MCU detects any other power disturbance, such as a voltage spike, the system shuts itself down. If this occurs, simply disconnect power from the MCU, wait 20 seconds, then restore power.
Blown Fuse
The antenna unit is equipped with a 5-amp, 125-volt fast­blow fuse on the PCB module. The MCU is equipped with a 15-amp, 125-volt fast-blow fuse on its rear panel. If either of these fuses has blown or been broken, the system will not work. To access the MCU fuse, simply unscrew the fuse holder cap on the rear panel. For details on accessing the antenna’s PCB module fuse, refer to Section 5.5, “Replacing the PCB Module Fuse,” on page 98.
Figure 4-1
MCU Fuse
Low Power
If the power cable from vessel power to the MCU is more than 50 ft (15 m) in length, the power level can decrease over the course of the cable, resulting in a voltage level at the antenna unit that is too low to power the system. Refer to “Connecting Vessel Power and the MCU Ground Wire” on page 36 for details on supplying adequate power to the antenna unit.
Fuse
Improper Wiring
If the system has been improperly wired, the antenna unit will not operate correctly. Refer to Section 2.4, “Wiring the MCU,” on page 35 for complete system wiring information.
Vessel Turning During Startup
If the vessel turns during the two-minute startup sequence that occurs immediately after turning on the power to the TracVision G8, the antenna will record that variable motion as “standing still.” This may cause the antenna to track improperly. To solve this problem, turn the TracVision G8 off for at least 10 seconds. Then turn the system back on, ensuring that the vessel is either motionless or traveling in a straight line for the two minutes immediately following power-up.
Data/Power Cable Interference
Depending on how cables are routed, conducted emissions from the system’s data/power cable may cause reduced picture quality on your TV screen. If the picture quality degrades only when the TracVision G8 is operating, try installing the small ferrite coil supplied in the kitpack. Simply clamp it onto the data/power cable to reduce its conducted emissions (see Figure 4-2). You might also try grounding the receiver to a suitable earth ground.
Figure 4-2
Small Ferrite Coil
Troubleshooting
54-0198
87
Incorrect Satellite Configuration
(European Systems Only)
The satellite configuration on European receivers must match the satellite settings on the TracVision G8 system.
Satellite A on the TracVision G8 must be the same satellite as receiver Alternative 1 (or A, based on your receiver) and must be assigned the receiver DiSEqC 1 setting.
Satellite B on the TracVision G8 must be the same satellite as receiver Alternative 2 (or B, based on your receiver) and must be assigned the receiver DiSEqC 2 setting.
Refer to your receiver’s user manual for complete instructions on configuring your receiver.
Satellite Signal Blocked
Satellite signals can be blocked or degraded by buildings, other vessels, or equipment on the vessel itself. Refer to “Choosing the Best Location for the TracVision Antenna” on page 23 to make certain that the TracVision G8 antenna unit is in the optimal location. Simply moving the vessel to clear an external obstruction will also restore signal quality.
Satellite Coverage Issue
TracVision G8 will provide outstanding reception within the 32" (82 cm) antenna coverage area for your satellite television service of choice. However, signal quality can be degraded as you approach the fringe coverage areas. Refer to your satellite television service manual to check the viable coverage area for a 32" (82 cm) antenna.
Radar Interference
The energy levels radiated by radar units can overload the antenna’s front-end circuits. Refer to “Choosing the Best Location for the TracVision Antenna” on page 23 to make certain that the TracVision G8 antenna unit is in the optimal location with regard to your radar unit.

TracVision G8 Owner’s Manual - Guide to Technical Information
For your convenience, KVH provides links to several web sites that offer satellite coverage information. Simply go to our web site at
www.kvh.com/footprint
.
Satellite Frequency Data Changed
If some channels work, while one or more other channels do not, or the antenna cannot find the satellite, the selected satellite’s frequency data may have changed. To update this frequency data, refer to “Updating Satellite Frequency Data” on page 74.
Incorrect or Loose RF Connectors
As part of preventive maintenance (described in Section 5.2, “Preventive Maintenance,” on page 95) KVH recommends checking
the antenna unit’s cable connections. A loose RF connector can reduce the signal quality. In addition, if you are unable to switch satellites using your receiver’s remote, make sure that your receiver’s RF cable is connected to the antenna’s RF1 connector (see Section 2.3, “Connecting the Receiver(s),” on page 31).
Type of Multiswitch Used
An active (not passive) multiswitch must always be used to connect the TracVision G8 system to multiple receivers. Refer to Section 2.3, “Connecting the Receiver(s),” on page 31 for directions on proper multiswitch/multiple receiver cabling.
4.3 Receiver Troubleshooting
The receiver that was provided with your satellite television service may also be the cause of less-than-ideal operation. First check the receiver’s configuration to ensure it is set up for the desired programming. In the case of a faulty receiver, refer to your receiver’s user manual for service and warranty information. If the receiver is both configured properly and fully functional, contact your local KVH dealer or service center for assistance.
4.4 Antenna Gyro and LNB Faults
Section 5, “Maintenance,” provides detailed instructions for authorized service personnel who may be required to replace one of the antenna gyros or the LNB.
