Picture this mounted on the roof, cowling or fender. I ran about thirty of these on fleet vehicles and they lasted for years going through car washes and getting generally beat up. They have 3db gain, which doesn't sound like much, but they are just right for simplex and repeater use. You can also put one on a NMO magmount if you want to be able to move it. They still work well and are much easer to deal with than the larger antennas. If you are using for ham dual band then that's a different story. But for dedicated UHF/GMRS they work great.
