[TowerTalk] Radio remote control?

[Ian White G/GM3SEK]

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.
