Yeah i have a 2dbi and 6dbi set up, running off a gme unit. So far no issues. Connection and reception is quiet good. Do you have both hooked up at once, or plug the one in that most suits your needs at the time? My current unit is an older 40 channel, so I'll be going for a remote mic 80 channel, get a low dBi aerial and leave the current one. I had issues with the unit in my previous vehicle, and despite a new aerial it never worked great. Can't be bothered with the same issue, so get a new unit to start with....
