    3.4.2 COM Antenna Location The GTN COM antenna should be well removed from all projections, engines and propellers. The ground plane surface directly below the antenna should be a flat plane over as large an area as possible (18‖ square, minimum). The antenna should be mounted a minimum of six feet from any DME or other COM antennas, four feet from any ADF sense antennas, and two feet from the GTN and its GPS antenna.

    Locate the GTN 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. This filter is not required for the GTN transmitter.

  • Page 44: Gtn 625/635/650 Mounting Considerations

    GTN 625/635/650 Mounting Considerations The GTN is designed to mount in the avionics stack in the aircraft instrument panel within view and reach of the pilot. The primary unit location should minimize pilot head movement when transitioning between looking outside of the cockpit and viewing/operating the GTN. The location should be such that the GTN unit is not blocked by the glare shield on top, or by the throttles, control yoke, etc.

  • Page 45: Air Circulation And Cooling

    Air Circulation and Cooling CAUTION To avoid damage to the GTN, take precautions to prevent Electro-Static Discharge (ESD) when handling the GTN, connectors, fan, and associated wiring. ESD damage can be prevented by touching an object that is of the same electrical potential as the GTN before handling the GTN itself.
