 |

Hi All,
If I have more than one com radio do I need an antenna for each and if yes how close to each other can I put the antennas. This will be in a composite aircraft and the antennas will hopefully be in the vertical stabilizer
Thanks
Mike

There are a couple of switch devices that allow you to do this. However, I would use two antennas with two radios - check the archives for the distance requirements and a discussion of this topic.
I have two radios - and two antennas - one on top and the other on the bottom.

Yes, two antennas are called for with dual comm transceivers.
The antenna sharing "switches" for comm transceivers are
problematic. You'll need to separate the antennas. How about
one in the vertical fin and the other on the belly?

I have a Narco automatic antenna switching device that I'd be happy
to sell for $25 plus shipping. Please contact me off list if anyone is
interested.
