GL-DYJ350B 300-390 MHz 12 dBi Yagi Antenna

Wideband UHF Yagi

The GL-DYJ350B is a twelve-element UHF Yagi notable for its wide 300-390 MHz coverage, the broadest in the UHF beam family, delivering 12 dBi from a 1.8 m boom. The wide match means one antenna can serve several different UHF allocations or a system whose channel plan spans a large part of the band, which simplifies stocking and reuse for integrators and operators who work across multiple 300-390 MHz networks.

Directivity Across a Wide Band

Twelve elements provide a tight forward lobe and strong rejection of rearward signals while holding gain steady across the full 90 MHz span. That consistency matters on a wideband beam, where lesser designs lose gain or match at the band edges. The pattern keeps the link efficient and reduces interference from other directions, and the boom can be mounted for vertical or horizontal polarization to suit the far-end station.

Construction

The antenna feeds a 50 ohm line through an N-female connector, with customisation available, and is rated for 100 W. The 1.8 m boom is designed for outdoor pole mounting, and the weatherproof hardware and 60 m/s wind rating support permanent fixed-link installations. Despite the higher element count it remains a manageable single-boom antenna for one installer.

Where It Works Best

• Multi-channel UHF links spanning much of 300-390 MHz
• Integrator stock antenna for varied UHF deployments
• Directional backhaul for telemetry, SCADA and data
• Fixed links where wideband flexibility is valued

Selecting the Model

Use GL-DYJ350B when wide frequency coverage is the priority. For a narrower band at higher gain, the 15-element GL-DYJ350C and stacked GL-DYJ350F focus more energy, while the 8-element GL-DYJ350A is a lighter choice. Confirm your channels fall within 300-390 MHz and check the connector option before ordering.
