Overview

The GL-DY350BII is a UHF fiberglass omni antenna for 330-400 MHz repeater, telemetry, paging, dispatch and fixed RF coverage sites. It gives installers a vertical omni pattern for outdoor base-station coverage where the antenna needs to serve users around the mast rather than in a single directional sector.

RF Performance

The source specification lists 330-400 MHz, 8.5 dBi gain, 100 W maximum input power and N female or customization connection. Bandwidth is listed as 14 MHz, VSWR as <= 1.5, and the feed system uses 50 Ω impedance, keeping the antenna aligned with common land-mobile, telemetry and fixed wireless radio equipment.

Build and Installation

Mechanically, the antenna uses a 2.5 m fiberglass radome profile, 3.2 kg weight, vertical polarization and 60 m / s rated wind velocity. The product notes specify Fiberglass. Install it on a suitable mast or bracket, keep the feed cable strain-relieved, and confirm grounding, lightning protection and site clearance before commissioning.

Typical Applications

Repeater and base-station coverage for private radio networks
Utility, campus, mining, security and industrial telemetry systems
Paging, dispatch and fixed site monitoring links
Outdoor RF test sites that require an omni reference antenna

Selection Notes

Choose GL-DY350BII when the radio plan matches 330-400 MHz and a vertical omni pattern is preferred over a directional yagi or panel antenna. Confirm the exact operating channel, connector, mast hardware, cable assembly, wind exposure and any customization requirements before ordering.
