John,

William Donzelli can give you the real technical info on how the switching
unit does its job, but until he replies I'll provide what the ASB-5
operating manual that I got from Fair Radio says.  There are only two (port
and starboard) antennas for the ASB.  They connect to the antenna switching
unit CRR-14AAG.  Also connected to the CRR-14AAG is the transmitter RF
output cable, the receiver RF input cable, the receiver output cable, the
indicator unit's port and starboard input cables, and the power cable to the
rectifier unit.  That's a bunch of cables and I'm not sure what some of them
do, but there are only the two antenna cables.
