• Before beginning any work on the antenna unit, turn off the breaker for the de-icer
at the mains switchboard. (Turning off the display unit has no effect.)
• 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 heats to
55°C.)
Wrap the spiral tubing near the crimp-on lugs.
