1.2 Equipment Description
The Garmin GDL 50/50R/51/51R/52/52R products are not TSO-certified products and have received no
FAA approval or endorsement. These products can provide the following data: GPS, SiriusXM weather/
audio, ADS-B traffic and weather, attitude and pressure to compatible displays and audio devices via
Bluetooth® wireless technology and/or over wired connections.
The GDL 52/52R data link products include internal WAAS-enabled GPS, dual-band ADS-B & SiriusXM
receivers, and attitude & pressure sensors. The GDL 51/51R product provide the same functionality except
for the dual band ADS-B receiver. The GDL 50/50R products provide the same functionality except for the
SiriusXM receiver.
The GDL 5X provide these functions in a portable form factor that includes applicable internal
GPS/SXM/ADS-B antennas, and an internal battery. The GDL 5XR products are remote mount versions
that require external antennas and power connections. No battery is provided in the remote mount
versions.
The GDL 50/50R/52/52R receives Traffic (ADS-B/ADS-R and TIS-B) on both Universal Access
Transceiver (UAT) and 1090 ES (Extended Squitter) frequency bands. When in range of a ground station,
these units will receive FIS-B weather over the UAT link.
The GDL 5X/5XR products provide this information to Garmin® units like the aera 660/795/796, G3X
Touch displays and devices running Garmin Pilot™. These products will request this information over a
Connext® data connection. Please see additional information in the pilot's guide for your display.

The GDL 5X/5XR products can use Bluetooth wireless technology to create Connext® connections to
display devices. For optimal wireless performance ensure that the unit has an unobstructed view of the
Connext enabled devices.
GDL 5XR mounting location will vary for each installation depending on aircraft body type (metal or
fiberglass) and the surrounding structures/equipment. For best performance, mount the GDL 5XR with the
front of the unit (LEDs and connectors) facing the cockpit and centered laterally between the two aircraft
sides.
The GDL 5X Connext wireless antenna is located on the front face of the unit as shown in the red rectangle
in Figure 2-1.

rectangle in Figure 2-2 below.
Figure 2-2 GDL 5XR Connext Antenna Location
Do not install the GDL 5XR in a metal box or beneath a floor panel, as this will attenuate (decrease) the
wireless signal. If the installation contains another device that uses Bluetooth wireless technology, mount
the devices apart from each other as much as possible (at minimum, leave a small gap between the devices)
to prevent signal interference.
If poor Connext wireless performance is observed, check the auto reconnect settings and
disable any devices that are not intended to be used.
2.6 Cabling and Wiring
Refer to the interconnect examples in Appendix B for wire gauge guidance.
If using larger barrel contacts, ensure that no two contacts are mounted directly adjacent to each other. This
minimizes the risk of contacts touching and shorting to adjacent pins and to ground.
Use wire and cable meeting the applicable aviation regulation. When routing wire and cable, observe the
following precautions:
• Keep wire and cable as short and direct as possible
• Avoid sharp bends
• Avoid routing near power sources (e.g. 400 Hz generators, trim motors, etc) or near power of
fluorescent lighting
• Route the GPS, ADS-B, SiriusXM antenna cables as far as possible away from all COM
transceivers and other antenna cables.
• RG400 or RG142 coaxial cable with 50 Ω nominal impedance and meeting applicable aviation
regulations should be used when installing optional external antennas.
Avoid installing the unit near heat sources. If this is not possible, ensure that additional
cooling is provided. Allow adequate space for installation of cables and connectors. The
installer will supply and fabricate all of the cables.

2.7 Cooling Air
NOTE
The GDL 5X/5XR does not have provisions for attaching cooling air, however the thermal characteristics
of the installation should always be assessed. An undesirable thermal condition could be created due to the
unit's own internal power dissipation combined with restricted ventilation, or due to heat generated by
adjacent equipment. Limiting thermal build up, by means of fan or natural convection is always a good
practice and recommended to increase the product lifespan.
2.8 Configuration, and Adjustment Options
The GDL 5X/5XR has several configuration/adjustment options. More information about these
configuration items can be found in the connected display pilot’s guide. The configuration/adjustments are
as follows:
• Cabin Pressure Setting
◦ Pressurized Cabin or Unpressurized Cabin
• Attitude Sensor Reset
◦ Use this to zero the pitch/roll to the current aircraft attitude.
• Compatibility Mode
◦ Using this setting may improve Garmin Pilot Connext data connections.
• Auto Reconnect Settings for paired wireless devices
The GDL 5X/5XR products can simultaneously support up to: 2 wireless display devices, 1 wireless audio
device, 2 wired display devices, and 1 wired audio device.
If poor Connext wireless performance is observed, check the auto reconnect settings and
disable any devices that are not intended to be used.

2.11 Noise
To reduce noise on the audio lines, care must be taken to minimize effects from coupled interference and
ground loops.
Coupled interference can sneak into audio system interconnecting cables when they are routed near large
AC electric fields, AC voltage sources, and pulse equipment (strobes, spark plugs, magnetos, EL displays,
CRTs, etc). Interference can also couple into audio system interconnecting cables by magnetic induction
when they are routed near large AC current-carrying conductors or switched DC equipment (heaters,
solenoids, fans, autopilot servos, etc).
Ground loops are created when there is more than one path in which return currents can flow, or when
signal returns share the same path as large currents from other equipment. These large currents create
differences in ground potential between the various equipment operating in the aircraft. These differences
in potential can produce an additive effect at an audio panel signal input.
The audio panel may "see" the desired input signal plus an unwanted component injected by ground
differentials, a common cause of alternator-related noise. This is the main reason why all audio jacks
should be isolated from ground. Terminating audio shields just at one end eliminates another potential
ground loop injection point.
Single-point grounding cannot be overstressed for the various avionics producing and processing audio
signals. Single-point, in this context, means that the various pieces of equipment share a single common
ground connection back to the airframe. Good aircraft electrical/charging system ground bonding is also
important.
The wiring diagrams and accompanying notes in this manual should be followed closely to minimize noise
effects.
2.12 Mounting Requirements
The GDL 5X/5XR mounting surface must be capable of providing structural support.
The GDL 5X is mounted using a GDL 5X mounting bracket (Appendix A-4
installation instructions.
The GDL 5X/5XR includes a sensitive attitude measurement sensor. Consider the following when
selecting a mounting location:
• Mount the unit with the FWD arrow aligned to within 3.0° of the longitudinal axis of the aircraft
(LED bezel parallel to the wing spar). Mount the GDL 5XR so that the connectors point in the aft
direction.
• The unit can be mounted with the serial tag pointing straight up or straight down, within 30
degrees of a level flight position.
• Using the connected display, cage the gyros while the plane is in a level flight position.
• For proper attitude performance the unit should be rigidly mounted to the aircraft.
• The unit should be mounted to the aircraft with the LED bezel facing toward the rear of the
aircraft.
• To prevent degraded accuracy, avoid placing the unit near areas that are prone to severe vibration.
• The mounting location for the unit should be protected from rapid thermal transients, in particular
large heat loads from nearby high-power equipment.

3.7 Antenna Installation
3.7.1 ADS-B Antenna Installation
The GDL 50/52 units include an ADS-B antenna. An optional blade-type ADS-B antenna mounted on the
bottom exterior of the aircraft can be connected to the GDL 50/52 via a cable connection to the unit's MCX
connector.
The GDL 50R/52R requires an external ADS-B antenna for reception. The antenna should be mounted on
the bottom of the aircraft and located at least 3.3 feet from high power transmitting antennas such as VHF
Comm, HF transmitter, DME, Transponder, and Radar. The connection is made by attaching the cable
from the external antenna to the BNC connector on the GDL 50R/52R. The GDL 50/50R/52/52R requires
a UHF antenna that meets the following specifications:
• Standard 50 Ω vertically polarized antenna with a VSWR < 1.7:1 at 978 MHz and < 1.5:1 at
1090 MHz.
• TSO-C66, TSO-C74, or TSO-C112 antennas that also meet the VSWR specification.
3.7.2 GPS/SiriusXM Antenna Installation
This section contains general information as well as installation information for GPS/SXM antennas.
Garmin recommends the antennas shown in Table 3-6
specifications listed in Table 3-3 will work with the GDL 5X/5XR GPS external antenna input. Any
equivalent antenna that meets the specifications listed in Table 3-4
external SiriusXM antenna input.
. However, any equivalent antenna that meets the
will work with the GDL 5X/5XR
The GDL 5X can receive GPS position information using the unit's internal antenna or by connecting an
external antenna via the MCX connector. It is recommended to verify the ability of the GDL 5X to receive
GPS information via the internal antenna as GPS reception quality is dependent upon the installation. The
GDL 5X/5XR can receive GPS information with any connected aera or GDU 4XX display.
A GPS antenna is not required to be connected to a GDL 5XR when the unit is connected to a Garmin Aera
660/795/796 or GDU 4XX display. For best performance, mount the GPS, SiriusXM antennas on top of
the aircraft and at least 3.3 feet away from all high power transmitting antennas.
Although no ground plane is required, the antenna typically performs better when a ground plane is used.
The ground plane should be a conductive surface as large as practical, and is typically made of either
aluminum sheet or wire mesh.
