I'd have to look at the unit. It's a few years old. I ordered a newer unit last night that I'm hoping does better. I ran with info I found earlier in the thread with regard to antenna extensions, but in retrospect thinking I probably grounded the system out while extending the antenna and killed the batteries. I think the unit I had claimed reception up to about where I'm at for range, so I'm hoping the newer units claim of a half mile range hold true. I'll know soon. I'm running off battery power for the receiver, and suspect that decreases range a bit as opposed to being able to plug into a power source.
