Regardless of whether I am listening on my 106, or 396 mobile, there is always a problem with the reception. I live in Gwinnett. I use the short racing duck that the shack sells. Its like 1.75" tall. Actually is on the 450MHz band and works well. I have a tower close enough that I don't even need an antenna. Make sure your squelch is somewhere between 10-11pm on the radio. Really helps too. If you can go into the software and turn Roam off, it will help with the reception.
