Re: Coupling Radio antennae

You could connect both antennas with a hybrid splitter but there would be > 3dB loss; which might be OK.  A better way is to use a 12 VDC BNC relay, like this one BNC relay, controlled with a switch on the panel. Do not switch it while transmitting and put the normal antenna on the normally closed side.

Subject: [c-a] Coupling Radio antennae



Since I had my mid-air, in which I lost my left winglet and associated radio antenna, I want to avoid the possible loss of radio contact, if this ever (very unlikely) happens again.  It was fortunate that my radio was connected through my right winglet, so I maintained radio contact with the tower.


I have now rebuilt my left winglet and associated radio antenna.  It works.  Is it possible to connect both antennae to the radio through a splitter (or combiner??) so that, if one antenna goes bad, or is knocked off by an errant airplane, radio contact is maintained?


Anxious to know.
