Comet GP-9N Dual-Band Base Antenna 2m/70cm 144/440 MHz High-Gain 17-Foot Fiberglass Vertical VHF/UHF Antenna with N-Type Connector for Amateur Ham Radio Base Stations

The Comet GP-9N Dual-Band Base Antenna is Comet’s highest-gain fiberglass vertical antenna for serious amateur radio operators who demand uncompromising signal strength and rugged outdoor reliability. Operating across the 2-meter (144 MHz) and 70-centimeter (440 MHz) amateur bands, this antenna provides exceptional gain—8.5 dBi on VHF and 11.9 dBi on UHF—ensuring strong, clear communication over extended distances. Built from high-grade fiberglass and precision-engineered aluminum hardware, the GP-9N is designed to survive harsh weather conditions including strong winds, rain, snow, and intense UV exposure. The 17-foot length and efficient phasing element design enhance radiation efficiency, extending both transmit and receive range for simplex and repeater operations. The antenna’s factory-tuned dual-band system offers broad frequency coverage with a low VSWR, eliminating the need for on-site adjustments. The N-type connector ensures excellent power handling and minimal signal loss, making it compatible with high-performance coaxial cables and modern VHF/UHF transceivers. Installation is straightforward with the included heavy-duty mounting hardware, providing a stable and secure setup for towers, masts, or rooftops. With its vertical polarization and 360-degree omnidirectional coverage, the Comet GP-9N is ideal for home base stations, repeaters, emergency networks, and amateur radio clubs.
