Topband: Remote receive antenna selection on topband?

How do the big remote stations handle receive antenna selection?

I will be doing my first ever remote operation this weekend for NAQP SSB,
and I have a hack at home, where I use the "Stereo" output on parallel port
from N1MM to drive a relay to select one of two receive antenna directions.

But any big topband station has much more complex receive antenna system
available and wondering how this is done remotely.
