Re: Coupling Radio antennae

Mike Satchell

After looking at the diplexors and triplexors, looks like these all have bandpass filters for two or more different bands, so probably is not a viable option for two VHF antennas using the same band.

Something like a coax switch might be an option, but typically each connection added between the radio and antenna adds 3 dB of loss.

Might consider carrying a portable since it has its own battery and antenna.

Congrats on getting back in the air Marc!

A "diplexor" might work for you (one radio/two antennas). Might check with them to be sure you get the type of connectors you want and matches your application.

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.
