Description
420–520 MHz UHF Omnidirectional Base Antenna
2 dBi omnidirectional white fiberglass base antenna for 420–520 MHz UHF systems.
The Purchase Radios PR-BASE-420-520-2dBi is a commercial-grade fiberglass base station antenna engineered to deliver wideband omnidirectional coverage across the entire 420–520 MHz UHF frequency spectrum. Built around a high-efficiency silver-plated brass radiator and feed structure, this antenna provides 2 dBi nominal gain with a 70° vertical half-power beamwidth, making it an ideal choice for land mobile radio (LMR) systems, fixed base stations, bi-directional amplifiers (BDA), and UHF repeater sites.
Designed to withstand extreme outdoor conditions, the Purchase Radios PR-BASE-420-520-2dBi features a high-strength, filament-wound white fiberglass radome capable of enduring operational wind speeds up to 200 mph (322 kph) and survival gusts up to 224 mph (360 kph). The base is equipped with a silver-plated brass Type N female jack connector and features DC grounding across the structure to dissipate static buildup and enhance lightning protection for connected radio equipment. With 150-Watt power handling and low VSWR performance, this antenna offers reliable long-term service for utility, public safety, industrial, and commercial wireless networks operating under FCC Licensing standards.
