coupler can be mounted horizontally or vertically depending on the location.
(Refer to Pgs. 3-14 through 3-18 of the Installation Manual)
2) Connect the antenna wire from the antenna to the insulator at the top of the
coupler. Keeping the length as short as possible.
3) Fasten the supplied ground strap to the connection provided at the base of the
antenna coupler. Make certain this connection is brazed or welded to the ship's
hull or ground system. The exposed ground strap should be painted or coated
with a material to prevent rust.

to the transceiver unit. The first cable is the receive cable and will connect to the
RX ANT port in the transceiver and to TB1 on the BK RELAY in the antenna
coupler. The second cable is the transmit cable and will connect to the TX ANT
port in the transceiver and to TB1, TX ANT on the antenna coupler board.
7) Reinstall antenna coupler housing using only a couple of the provided screws.
This will allow easier access when testing the unit later in the install.
Fasten the cable clamps in the transceiver, but do not install the covers until
