I'm using sdrTrunk V0.3.0--alpha1 to listen to a P25 trunking system. I have 2 SDR's each hooked up to a separate antenna. One antenna is better than the other. Which antenna should I use to monitor the control channel?

I realize this is a general question, and I'm interested in a general answer :).

I use a simple y cable to allow both dongles access to the same antenna. No loss of gain that I can tell. I'd use the better gain antenna on the voice dongle; but that's just me.

I too use 1 antenna for my sdr. I have an airspy and 2 crap dongles all on the same antenna. I have not noticed any loss either.

I would use the better antenna for the voice, and the other antenna for the control channel. The site's control channel antenna is constant, while the voice channel antennas alternate around the tower. - Tom
