[TenTec] Antenna switching

[JACrux <G3JAG@patents.freeserve.co.uk>]

Looks like there is more choice than I thought, but the one thing to avoid is 
firing RF into another rig instead of an antenna. My back to back Heathkit 
switches do this for me; the one leading to the antennas is switched to 
ground when not in use, so I could send RF into a dead short I suppose.  But 
if I hear no signals, I check the switch first .... Its either switched to 
ground or to the dummy load. Both give low signal strength on receive .... 
That also happens if my feedline is bust so switching antennas can be a quick 
way of checking for a serious fault in the antenna
