X300 Dual-Band Antenna – High Gain, Wide Coverage, and Rugged Design

The X300 dual-band base antenna is designed for amateur radio operators seeking exceptional VHF and UHF performance with increased gain and extended communication range. Operating on 144/430 MHz, the X300 delivers an impressive 6.5 dBi gain on 144 MHz and 9.0 dBi gain on 430 MHz, helping to maximize signal strength for both local and long-distance contacts. Its robust fiberglass construction is engineered to withstand harsh outdoor conditions, while the 3.1-metre design provides outstanding omnidirectional coverage for fixed-station installations. With a maximum power handling capability of 200W, low VSWR, and a durable weather-resistant design, the X300 is an excellent choice for serious amateur radio operators who demand reliable performance, enhanced coverage, and clear communications across both bands.
