Atlantic Radio ATL-BASE-420-520-2dBi UHF (420-520 MHz) Base Antenna

Base Station Antenna 2 dBi omnidirectional white fiberglass base antenna for 420–520 MHz UHF systems. The Atlantic Radio ATL-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 Atlantic Radio ATL-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. Key Features & Benefits Wideband 420–520 MHz Coverage: Operates across the full UHF land mobile frequency band with low VSWR performance (<1.5:1 from 440–470 MHz). High Wind Survival Rating: Filament-wound fiberglass radome withstands operational winds up to 200 mph and survival gusts up to 224 mph. Atlantic Radio ATL-BASE-420-520-2dBi Power Handling: Handles continuous RF input power up to 150 Watts for high-duty-cycle repeaters and base transceivers. DC Grounded Lightning Protection: Direct-current grounded radiation structure dissipates static charge to protect sensitive receiver electronics. Silver-Plated Brass Feed Structure: All-brass internal radiator with silver plating maximizes electrical conductivity and signal efficiency.
