Two transmitters, one antenna
« on: February 18, 2016, 12:21:55 AM »

May I use a coax 'T', or must I use an antenna switch if using two radios and one antenna.

Curious what would happen if one radio transmitted, while the other was on.    and what if it is off?

If a switch is required, it would be outside and that would be a pain.


Thanks all

You do NOT want to use a "T" between the radios.  Good possibility of damaging one of the receivers.  A switch is a good alternative or a "coupler" which could be placed outside if within some type of housing. You can couple two antennas to one radio or two radios to one antenna. You'll need to check the specifications regarding bandwidth, power rating and Db of separation.  DX Engineering is one of many distributors who offer them.
