2.7 Unit Installation
The Garmin Device is installed by holding the unit flush with the instrument panel and fastening the four
3/32” hex socket head screws to the panel as shown in Figure C-1.1 and C-1.2.
2.8 Continued Airworthiness
Maintenance of the Garmin Device is “on condition” only. Periodic maintenance of the Garmin Device is
not required. Instructions for Continued Airworthiness (ICA) are not required for this product under 14
CFR Part 21 since the Garmin Device has received no FAA approval or endorsement.
2.9 Panel Cutout Template
A template that can be used for marking the panel for cutout is available from www.garmin.com. See
Figure C-1.3 for complete dimensions.
This section contains general information as well as installation information for GPS and SiriusXM
antennas. Use this section to mount the GPS/SiriusXM antenna(s).
In an installation with multiple Garmin Device units, each Garmin Device can be configured to use its own
internal GPS receiver, or to receive GPS data transmitted by another Garmin Device. A minimum of one
GPS antenna is required for installations using more than one Garmin Device unit, as the Garmin Device
will “share” the GPS information with all Garmin Device units. Additional GPS antennas may be used for
redundancy, but are not required.
Only a single GPS antenna is required for installations using more than one
Garmin Device unit, as the Garmin Device will “share” the GPS information with all
Garmin Device units.
If using a Garmin GA 26C or GA 26XM, refer to the accompanying installation instructions
(190-00082-00 or 190-00522-03). For GA 55/55A, or GA 56 or GA 57X antennas, refer to this section
and the outline and installation drawings beginning with Figure C-1
.
Garmin recommends the antennas shown in Table 3-1. However, any equivalent GPS or SiriusXM
antenna that meets the specifications listed in Table 3-2 and Table 3-3
*For each 1 dB gain over 24 dB, add 1 dB of attenuation into the antenna cable path between the
antenna and the Garmin Device.
It is the installer’s responsibility to ensure that their choice of antenna meets FAA standards according to
the specific installation. This installation manual discusses only the antennas listed in Table 3-1
antennas may be acceptable but their installation is not covered by this manual.
There are several critical factors to take into consideration before installing an antenna for a satellite
communications system. These factors are addressed in the following sections.
3.2 Antenna Mounting Considerations
® Satellite Radio Antenna Minimum Requirements
. Other
The information in this section does not pertain to in-cabin (internal) mounted antennas such as the
GA 26C, refer to the accompanying installation instructions (190-00082-00).
No special precautions need be taken to provide an electrical bonding path between the GPS Antenna and
the aircraft structure.
3.2.1VHF COM/GPS Interference
On some installation VHF COM transceivers, Emergency Locator Transmitter (ELT) antennas, and
Direction Finder (DF) receiver antennas can re-radiate through the GPS antenna. The Garmin Device does
not interfere with its own GPS receiver. However, placement of the GPS antenna relative to a COM
transceiver and COM antenna, ELT antenna, and DF receiver antenna is critical.
Use the following guidelines, in addition to others in this document, when locating the Garmin Device and
its antennas.
•GPS Antenna—Locate as far as possible from all COM antennas and all COM
transceivers, ELT antennas, and DF antennas. The GPS antenna is less susceptible to
harmonic interference if a 1.57542 GHz notch filter is installed on the COM transceiver
antenna output.
•Locate the Garmin Device as far as possible from all COM antennas.
If a COM antenna is found to be the problem, a 1.57542 GHz notch filter (Garmin P/N 330-00067-00) may
be installed in the VHF COM coax, as close to the COM as possible.
If a COM is found to be radiating, the following can be done:
1. Replace or clean the VHF COM rack connector to ensure good coax ground.
2. Place grounding straps between the Garmin Device unit, VHF COM and a good ground.
