ST94-21 C/Ku-Band TVRO Introduction
1.5. Dual Antenna Arbitrator
The Dual Antenna Arbitrator panel can pass LNB voltages (and handle 250-400 ma of current) and the RXIF signals on
the RX connections.
The blockage (SW2) output from the two terminal mounting strips (antenna “A” and antenna “B”) are wired through
the arbitrator panel to the satellite receiver distribution. When antenna “A” is blocked, the arbitrator PCB will toggle
the coax switches so that antenna “B” provides signal to the BDE distribution (multi-switch). When antenna “A” is no
longer blocked the arbitrator will do nothing (because it is a latch circuit). When antenna “B” is blocked the panel will
switch so that antenna “A” is again providing signal the BDE distribution.
