When the De-icer is installed:
1. Before beginning any work on the antenna unit, turn off the breaker for the de-icer
line at the main switchboard to remove the power (100 VAC, 1
) to the de-icer.
(Turning off the power to the display unit has no effect.)
2. The neck of the antenna unit becomes VERY HOT when the de-icer is working.
(The de-icer turns on when ambient temperature goes down to 5°C and goes up
to 55°C.)
Coaxial cable
When connecting the coaxial cable to the antenna unit, follow the steps below.
1. Unfasten eight bolts (M6x20) to remove the flange cover from the antenna unit.
2. Apply grease to the O-ring located in the flange.
3. Coat between mating surfaces of the coupler at the end of the coaxial cable and
waveguide flange as below with waterproofing compound (supplied with installa-
tion materials). Do not coat the O-ring.
4. Screw eight bolt unfastened at step 1 to fix the coupler to the flange.
