Connecting the antenna cable

Manufacturers recommendation:
First connect the antenna cable to the terminal board at the antenna box, then install the
Antenna Unit to the ship's mast.

-- Strip the complete cable entry over the antenna cable (see Figure 32).
-- Strip off the shielding to a practicable length of cores. The shield should be stripped
off in a way such that the cores can be led from the cable inlet to the terminal board
without mechanical stress.
Too long cable cores can lead to EMC problems.
-- Lead the cable through the cable inlet of the housing (strain and counter nut outside
and cone with shielding crimp inside the housing)
-- Connect the screen (separate core) to the cone.
-- Fasten the cable inlet with the counter nut.
-- Connect the cores to the terminal board B1 (note the core colors) (see Figure 33)
according to appended drawings or to the table below.
