Mount to a RocketDish Antenna

This section applies only to the airFiber AF-4X and AF-5X
radios.

Note: If you are mounting the AF-4X or AF-5X on

a RocketDish equipped with the AF-5G-OMT-S45
Conversion Kit, the Universal Bracket is not needed.
Refer instead to the Mount to an airFiber X Antenna
section for instructions.

The RocketDish RD-5G30 antenna is shown in this section:

1. Position the Universal Bracket over the back of the
airFiber radio with the bracket clips over the radio
mounting tabs.

2. Push the bracket onto the airFiber radio until it locks in
place.

Mount the External GPS Antenna

Locate a mounting point that has a clear view to the
sky, and is above and as far away as possible from the
airFiberX radio.

1. Attach the GPS Antenna Mount to the pole using the
metal strap, or attach it to a wall using the appropriate
fasteners (notincluded).

2. Place the External GPS Antenna on the mount.

3. Attach the airFiber radio to the RocketDish mounting
bracket.

a. Align the mounting tabs on the Universal Bracket

with the RocketDish mounting bracket.

b. Slide the airFiber radio down to lock it into place.

3. Secure the cable of the External GPS Antenna to the

mount with a Cable Tie.

Connecting Power over Ethernet

1. Lift the release latch on the bottom of the airFiberX
radio and slide the Port Cover off.

2. Connect an outdoor, shielded Ethernet cable to the
DATA port.

Mount the PoE Adapter (Optional)

1. Remove the Mounting Bracket from the adapter, place

the bracket at the desired location, and mark the
two holes.

2. Pre-drill the holes if necessary, and secure the bracket
using two fasteners (not included).

3. Align the adapter’s slots with the tabs of the Mounting
Bracket, and then slide the adapter down.

Surge Protection

For added protection, install two surge suppressors, such
as the Ubiquiti Ethernet Surge Protector, model ETH-SP,
at the end of each link. Install the first surge protector
within one meter of the airFiber DATA port, and install the
second surge protector at the ingress point of the location
housing the wired network equipment.

3. Connect the other end of the cable from the DATA port
to the Ethernet port labeled POE on the airFiber PoE
Adapter.

WARNING: Use only the included airFiber PoE

Adapter, Model: GP-H240-100G-4. Failure to do

so can damage the unit and void the product
warranty.

4. Connect an Ethernet cable from your LAN to the
adapter’s LAN port.

5. Connect the Power Cord to the adapter’s power port.
Connect the other end of the Power Cord to a power
outlet.

Alignment

Tips

• To accurately align the airFiberX radios for best

performance, you MUST align only one end of the link at
a time.

• You may need to use additional hardware to

compensate for issues such as the improper orientation
of a mounting pole or significant elevation differences
between airFiberX radios.

Note: If you have AF-5X radios mounted in an

airFiber Multiplexer (AF-MPx4 or AF-MPx8),
perform the procedure in “Establishing a Link”
on page9 on one radio only. This will help
ensure maximum success in registrations. Refer to

“AF-5X and airFiber Multiplexer” on page 45

for additional information on airFiber Multiplexer
installation.

Establishing a Link

Adjust the positions of the Master and the Slave to
establish a link.

Note: The Master must be aimed first at the Slave

because the Slave does not transmit any RF signal
until it detects transmissions from the Master.

Note: The airFiber X antenna AF-5G30-S45 is

shown in the following steps. Instructions for other
antennas are similar. For complete details, refer to
the Quick Start Guide for your specific model.

1. Master Visually aim the Master at the Slave. To adjust
the Master’s position:

a. Loosen the four pole clamp nuts, and rotate the

airFiber antenna on the pole to align the azimuth.

Chapter 2: InstallationairFiber X User Guide

Note: Do NOT make simultaneous adjustments

on the Master and Slave.

2. Slave Visually aim the Slave at the Master. To adjust the

Slave’s position:

a. Loosen the four pole clamp nuts, and rotate the

airFiber antenna on the pole to align the azimuth.

b. Loosen the six elevation bolts, and use the hex nut

on the elevation rod to adjust the elevation.

3. Check to see if a link is established. Ensure that the LINK
LED is solidly lit green and the Signal LEDs of the Slave
are displaying signal levels.

b. Loosen the six elevation bolts, and use the hex nut

on the elevation rod to adjust the elevation.

4. Slave Aim the Slave at the Master to achieve the
strongest signal level on the Master.

Note: Refer to “Signal LEDs” on page 2 for

details on the signal values.

Note: Maximum signal strength can best be

achieved by iteratively sweeping through both
azimuth and elevation.

5. Master Aim the Master at the Slave to achieve the
strongest signal level on the Slave.
