Installing Above Deck Unit (ADU)
5.4 Routing RF Cable on Mast
The cable must be routed from the antenna and through various areas of the ship to end up at the antenna
control unit. When pulling the cables in place, avoid sharp bends, kinking, and excessive force. After
placement, seal the deck penetration gland and tie the cable securely in place. The cable bracket must be
installed on the mast to fix the relevant cable. The gooseneck must be installed on the side of the mast to
protect the relevant cable against water.
WARNING
WARNING
Ensure that cable has been run through watertight fittings
to prevent water entry into the vessel when installation is
completed.
Option 1. Routing Cable Through Inside Mast
1. Before placing the radome on the mast, route the cable
through the gooseneck on the deck and the built-in
gooseneck on the mast for easier placing of the RF Cable
through the inside of the mast as shown in the picture.
2. Maintain a sufficient cable length (at least 2 m) when
routing the cable on the surface and inside of the mast.
After connecting the cable to the connector on the
radome, adjust the length and fix the cable on the cable
brackets using cable ties.
