The RFI CD28-37-50 VHF Mopole Antenna is a ground-independent, broadband solution covering 138 - 163 MHz with a 3 dB gain advantage over standard ¼-wave whips. Supplied with an MBC right-angle SO-239 roof-mount base (cable not included), the antenna features a patented matching circuit housed in a virtually indestructible thermoplastic body and a flexible, tapered stainless-steel whip that shrugs off knocks and bends. Its versatile, no-ground-plane design allows reliable performance when mounted on gutters, mirrors, trunks, or other non-traditional locations.
