I bought one of these to run on my Grand Cherokee with a 148GTL. A little info here, height is about the same as a Wilson 5000, magnet is pretty much as strong. Merely jamming the whip all the way into the mount and tightening the set screws gave me a 1.1:1 match on 27.205. The the upper-end I checked, just shy of 10 meters, match was 1.5:1. Very surprising. Very little noise, good receive, and a good transmit range local, about fifteen miles with a 4 watt carrier swinging to 10 watts at 100% modulation. DX-range was also good, no trouble running from here in Ohio to Washington (The State) both ways on LSB. Comes with a fourteen foot length of mini-8 coax and a pl-259. For less than half the cost of a Wilson 5000 Mag-mount(They run $85.00 or so around here) , actually $28.00 and change at Walmart of all places, it's a heck of a buy.
