I had a few issues with mine at first like a terrible squeal when I transmitted. I just redid the ground wire and made sure that the new ground was solid and it cleared all my issues up. I can for sure hear people much further out then they can hear me(transmit). This is just a very basic trail antenna and not so good at that either like I said if you get to much separation. On the highway I tested it once and got 4 miles I think, but keep in mind it was a straight long highway. 4xGuard sells an antenna mount and there are some home made ones as well.
