Can someone explain to me why some remote antenna switch manufacturers use
a scheme that supplies 12V to the relay box and switch the ground side of
the relays to select antennas, while others supply a common connection and
switch the 12V to the desired relay? I can't see an advantage one way or
the other, and it does have the effect of creating incompatibility among
makers' hardware.
