GIA 63 Installation Manual 190-00303-05
Page 2-10 Rev. Y
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. This filter is not required for the
GIA 63(X) transmitter.
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 GIA 63(X) unit, VHF COM and a good ground.
3. Shield the VHF COM wiring harness.
2.3 Rack Considerations
A location away from heating vents or other sources of heat generation is optimal. The GIA 63(W) can be
mounted using the G1000 system rack. The unit may be mounted remotely if desired. The GIA 63H must
be mounted in the Helicopter Rack.
