ljh505 Posted November 4, 2020 Report Share Posted November 4, 2020 I picked up a Browning BR-173-S spring base UHF antenna from a local business-band radio installer. This is a cut-to-tune (not a factory tuned) antenna. I have it mounted on a small coupe with a Diamond K400 series NMO trunk lip mount. Using a RigExpert AA-650 Zoom analyzer, I cut the antenna down to a 1.23:1 SWR on 462.8 MHz. This is my primary GMRS mobile antenna. I cut it to resonate at ~463 MHz rather than ~467 MHz as I usually operate simplex, not repeaters. A SWR sweep of the tuned antenna is attached.
