2.4 Other Installation Considerations
Prior to installing the antenna coupler, you should carefully assess the
location where the coupler will be mounted, specifically considering the
external connections to the coupler.
Prior to starting the installation, you should develop an installation
strategy by carefully reviewing all installation instructions, including
mechanical and electrical instructions.
Use appropriate appendices for guidance with antenna coupler
dimensions.
Installations not identified in applicabl
e STC’s may require additional
substantiation.
The antenna coupler is held in place by four screws. Refer to Appendix
C.
A positive ground path must be established between the datalink coupler
chassis and airframe ground less than 0.5 ohms.
2.5 Electrical Interfaces
Power to the datalink coupler is derived directly from the aircraft. The
coupler must be connected to the same circuit breaker as the comm it is
connected to. The coupler does not have an on/off switch. Refer to
Appendix A, Datalink Coupler Interconnect. Power, Ground and PTT are
all connected through the 9-pin male D shell connector available at the
front of the coupler.
