Perfect antenna, 5/8 wavelength 2 meter NMO style mounts (which I love) and it gets out well. Match is near perfect 1.2:1UPS slightly bent he whip, but a gentle tweak, all was as good as new. Thanks again. I got me neighbor ordering ham antenna gear from you guys too. In fact, I recruited him into ham radios. :D73 from Rick
