Might seem a little odd for a hunting gear review but we've all had run into shitty or no cell service at all while travelling to a hunt and I had always wanted to know if these things actually provided any benefit. I was quite happy with the performance.
Vernon Fish & Game club installed one at the range. Not sure what brand but it works fine. Larger system than something for a vehicle. Antenna mounted on the roof of the rifle range. Good thing to have in case of an emergency.
