Excellent antenna Time Owned: 0 to 3 months.
I've read on the forum that similar models of this antenna have succumbed to joint failure in the couple of joints in this antenna, but this has not yet happened to me. Therefore, my review may change considerably in the future.

However, I'm absolutely convinced this is the best mobile antenna money can buy. The SWR was 1.1:1 and usually even less all across both bands, and I was able to hold long-distance UHF simplex conversations on low power, much to my surprise. I put it on a sturdy magnetic mount atop my truck, so I'm a little concerned about trees, but I never park in parking garages (haven't since I became a ham). Expect to pay a good price, though...
