I have a Sennheiser 100 G3 kit and I'd like to add a second. Simple question, is there a reason I shouldn't go with the same frequency range (G)? I chose G based on the frequency finder on Sennheiser's site, and have had good luck with it in my area. I also have the wireless stick mic, and can see the benefit of being able to pair it with either kit.

As long as they're on different frequencies within the G range, they shouldn't interfere with each other when being used at the same time, correct?

that's correct. i've been using a pair of G2s in the same frequency range with no problems.

As you have already pointed out, you gain flexibility when all your transmitters and receivers are in the same band. I mix G1, G2 and G3 components all the time.

Thanks for the responses, Henry and Les. Ordering now.
