2.7 RF Interfaces
The coupler has three Female BNC connectors mounted on the front
face. These connectors allow the VHF comm radio and the datalink radio
to connect to the top mounted aircraft antenna. For connector locations,
refer to Appendix C.
2.8 Positioning and Mounting the Coupler
The coupler should be mounted close to the rear of the VHF comm radio
it will be connected to, and close to the datalink transceiver. The cable
used to connect the VHF comm and the datalink transceiver should be
as short as practical, to minimize the loss found in long cable lengths,
and must be constructed of RG-400 or equivalent cable.
2.9 Weight and Balance
Weight and balance computation is required after the installation of the
DC50 Datalink Coupler. Follow the guidelines as established in AC43.13-
1B, Chapter 10, Section 2. Make appropriate entries in the equipment list
indicating items added, removed or relocated along with the date
accomplished. Include your name and certificate number in the aircraft
records. DC50 Datalink Coupler weight is identified in the technical
specification section as 0.65 lbs.
