2.2 Antenna Unit
2.2.1 How to fabricate the cables
Three cables are connected to the antenna unit: the serial cable from the transceiver
unit, waveguide (FAR-3220W-BB/3320W) or microwave coaxial cable (FAR-
3230SW-BB/3330SW), and power cable for the de-icer (option).
Serial cable (TTYCYSLA-10)
Power cable (DPYCY-1.5) for de-icer
• Before beginning any work on the antenna unit, turn off the breaker for the de-icer
at the mains switchboard. (Turning of the display unit has not 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.)
