1. Use a ratchet or box wrench (diagonal 13 mm) to open port- and starboard-side covers on the
antenna unit.
2. Unfasten the gland nut for the signal cable and remove the gasket, flat washers (3 pcs.) and
gland cap. (The gland cap may be discarded.)
3. Fabricate the signal cable as follows:
a) Remove the vinyl sheath, armor and sheath by the amounts shown in the figure below.
b) Unravel the shield to expose cores.
c) Shorten cores (except coax) considering their locations on the terminal inside the antenna unit.
d) Shorten the shield, leaving 300 mm. Attach crimp-on-lug (FV5.5-4, yellow,

e) Remove the sheath of cores by 6 mm.
f) Unravel armor.
