Remote Switches are low voltage AC or DC with 200 ft
# 18 Ga. Two antennas to one feed, one or the other ?

Some (like the Heath I have) superimpose the switching voltage onto the rf
transmission line (coax), and need no separate control wire.

Two fixed yagis one north one south you select.

That could be one use. Most designs accomodate at least 4 antennas for a single
feed.
