Increase the range of your GMRS setup with Midland's Highland Tall antenna package. They provide 6.6 dB gain and help overcome obstacles like buildings, hills, and dense forests that would interfere with the signal. The durable fiberglass antenna sits on top of a heavy-duty spring to withstand tough trails and dense brush. Mounting requires a .5 inch hole and can be attached to a bracket or surface up to .25 inch thick.
