I'm starting to lay out a new HF/VHF home station on a 1-acre site...
and can already see the numbers of 200-500ft control cables expanding
out-of-sight.
Obviously there is a basic minimum of links that have to be hard-wired:
RF signal lines, AC/DC power rails and ground bonding. But there seems
no reason why a lot of the simple control wires (eg antenna select and
direction switching) couldn't be converted into radio links.
What I had in mind is a pair of radio modems that provide "virtual
wires". So each modem would have a big array of terminal strips -
whatever goes into one terminal strip, comes out the other. (Obviously
there has to be a power and some jumpering at the remote end, but you
see the basic idea.)
Does such a product exist? I've only seen units providing say 4 relay
closures, which are far too few. This application really needs a minimum
of 16 "virtual wires", with capability to add further blocks.
