Waveguide connection at antenna unit
The signal cable entrance (cable gland) is located directly below the waveguide outlet. If the
waveguide is installed downward from the waveguide outlet position using an E-bend
waveguide, you may not be able to insert the signal cable into the cable gland. To avoid this
inconvenience, shift the waveguide run left or right using an H-bend waveguide as shown
below.
The E-band and H-band waveguides are contained in the waveguide materials set 22X-CW
or 52X-CW.
E-bend type RWA-1030 B-107, Code No. 310-100-140
H-bend type RWA-1050 C-109, Code No. 310-100-180
When the de-icer is installed
•
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
Ф
) to the de-icer. (Turning off the
power to 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 is below 0˚C.)
