Wire the Antenna
Wire the Antenna
Follow these steps to connect the antenna cable to the
antenna’s N-type baseplate connector.
Route the Cable Belowdecks
1. Route the TNC-connector end of the antenna cable
belowdecks through the cable access hole. Leave an
adequate service loop, 14" (36 cm) in diameter, at the
antenna location for serviceability.
2. Route the TNC end of the cable to the BDU location
(you will connect it later). Always maintain the
minimum bend radius in the cable.

Remove the Cable Cover
To access the antenna’s connector, you first need to
detach the cable cover. Loosen the six #6-32 captive
screws securing the cable cover to the base. Set the cover
aside in a safe place.

Attach Second Foam Seal, If Needed
If you routed the cable through a hole under the antenna
(see
page 8 ), attach a second foam seal to the base of the
antenna. First, clean and dry the bottom of the antenna.
Then peel the paper backing from the foam seal and press
the foam seal firmly onto the underside of the antenna.
