Review on Tram 140MHz-170MHz + 430MHz-470MHz Dual Band NMO Antenna (1181): Efficient Wireless Communication Solution by Stacy Watkins

This is the third one I have. They are just great and work well. I have one on my car and one on my truck. I gave it to a friend and he loves it too. SWR ADJUSTMENT is not required. If you really want to reset it, you can make small adjustments. It's completely stupid to pay more for another antenna just because of the brand. For 98% of mobile communications, you will hardly find a better antenna in this price range.
