Title: Need relay controlled A/B coaxial switch--any ideas?
Post by: K8EA on September 03, 2018, 01:24:54 PM
I am in need of a coaxial switch for antenna selection for my remote control setup. I cannot seem to find one on the market. Would need to be one that would take say 12VDC and switch from antenna A to antenna B. Need to handle full legal limit. Any ideas/recommendations out there? This is for my RemoteHams server and KMTronic switch. Need to be able to switch antennas. Surely someone has done this. ALL SUGGESTIONS GRATEFULLY APPRECIATED.

i use https://www.farcircuits.net (https://www.farcircuits.net) 6 way and make my own A/Bs  ,the 6 way boards from far are little crude but they work and the price is right. 

To drive  them i use https://www.unifiedmicro.com/decoder.html (https://www.unifiedmicro.com/decoder.html) with add on hsd 9 drivers.

I've used one of these for a couple of years now, and am very happy with it:
