Function Description Comments
Antenna Control
11H Selects horizontal
polarization.
Connect pins 1, 2, or 3 to GND (pin 6 or 1 in Feed/Relay
Power below) to select desired polarization. If all are left
ungrounded, antenna defaults to right circular (RC)
polarization. Selecting Ant. Pol. option button options on color
LCD display panel causes each pin, in turn, to be grounded or
all to be ungrounded. When ungrounded, should have +24
volts DC returning from antenna.
22V Selects vertical
polarization.
33LCP Selects left circular
polarization.
