  • Page 20: Cabling & Wiring

    Use AWG #24 or larger wire for all connections unless otherwise specified by the aircraft manufacturer or Garmin. The standard pin contacts supplied in the connector kit are compatible with up to AWG #22 wire. In cases where some installations have more than one unit sharing a common circuit breaker, sizing and wire gauge is based on aircraft circuit breaker layout, length of wiring, current draw of units, and internal unit protection characteristics.

  • Page 21: Mounting Requirements

    Mounting Requirements The GMA 1347D mounting surface must be capable of providing structural support and electrical bond to the aircraft to minimize radiated EMI and provide protection from High-Intensity Radiation Fields (HIRF). The GMA 1347D is mounted using its own system rack. Figure 2-2 shows the GMA 1347D unit rack. The unit rack is fastened to the aircraft instrument panel using the nutplate kit and bracket kit listed in Section 2.2.1.

  • Page 22: Installation Approval Considerations For Pressurized Aircraft

    Installation Approval Considerations for Pressurized Aircraft Antenna and cable installations on pressurized cabin aircraft require FAA approved installation design and engineering substantiation data whenever such installations incorporate alteration (penetration) of the cabin pressure vessel by connector holes and/or mounting arrangements. For needed engineering support pertaining to the design and approval of such pressurized aircraft antenna installations, it is recommended that the installer proceed according to any of the following listed alternatives:...

Extracting the #16, #18 and #20 contact requires that the expanded wire barrel be cut off from the contact. It may also be necessary to push the pin out from the face of the connector when using an extractor due to the absence of the wire.
