2.24 ANTENNA INSTALLATION
The following paragraphs provide installation details for directional antenna. Standard installation
practices prescribed in FAA Advisory Circular No. 43.13 must be followed. The installer must ensure the
immediate antenna installation area is clean and prepared so that the antenna is electrically bonded
(metal-to-metal contact) to the aircraft. To provide optimum bonding through the mounting holes, prepare
the surfaces with Alodine No. 1001.
To facilitate mounting to the airframe, the dimensions shown in Figure 2-10 can be used to locate and drill
mounting and connector access holes. Connection to the antenna should be made in accordance with the
system interconnect diagram (figure 2-2, 2-3 or 2-4).
NOTE
A doubler plate (not supplied) is required to reinforce the aircraft skin.
1. Connect each of the three antenna cables. Check to ensure that each cable is connected to the correct
antenna connector. Each connector/cable has a matching color band (see note par.2.6.1).
2. Attach the antenna to the aircraft, with the special adapter plate and o-ring, using 10-32 hardware
provided. See Figure 2-11.
NOTES
1. When mounting the antenna remove the O-ring from the bag and install it
in the O-ring groove on the bottom of the antenna.
2. For pressurized aircraft, use a sealant that meets the requirements of SAE
AMS-S-8802 such as Flamemaster CS3204 class B. For non-pressurized
aircraft, use a non-corrosive sealant that meets the physical requirements
of MIL-A-46146 such as General Electric RTV162.
