Hi - I'd like to switch between 4 or 8 different rx antennas by a GUI on a
Windows desktop, so that I can control RX antenna selection from locations
remote from the shack (e.g., accessed remotely using screen-sharing
software such as AnyDesk).

Can someone point me in the right direction to start looking?  I see
8-relay USB boards are a commodity, and some vendors (e.g., Denkovi) offer
associated Windows GUI control software.  It seems a relatively
simple matter to outfit such a board with coax connectors, etc.,  and be up
and running.  But perhaps there are alternative solutions I should consider?

(I see DX Engineering has a  DXE-RR8B-HP system that runs $500 - $800.  I'm
interested in a less expensive solution.)

Tnx for input,

/Bill, K2PO
