Overview

The GL-DY350AT3 is a UHF fiberglass omni antenna for fixed radio coverage, repeater sites, telemetry networks and private wireless systems that need dependable 300-390 MHz operation. It provides an omnidirectional vertical pattern for sites where users or devices are distributed around the mast rather than concentrated in one direction.

RF Performance

Its core RF specification is 300-390 MHz, 3 dBi gain, 100 W maximum input power and N Female connection. Bandwidth is listed as 10 MHz, VSWR as <= 1.5, and the feed is 50 ohm, making the antenna suitable for base-station, repeater, monitoring and engineering systems that match the source frequency plan.

Build and Installation

The antenna uses a 0.6 m outdoor structure, 0.4 kg weight, vertical polarization, 60 m / s wind rating. The source notes identify the construction or installation note as Fiberglass it c an be installed with M110 magnetic mount or pole, so this listing keeps the claim tied to the original data. Confirm the mast, bracket, feeder cable and lightning protection plan before installation.

Typical Applications

VHF/UHF repeater and base-station coverage
Utility telemetry, paging and dispatch networks
Rooftop, mast and tower installations
Fixed RF test sites and engineering labs

Selection Notes

Choose GL-DY350AT3 when the site needs omnidirectional coverage with the frequency and gain profile above. If the path needs sector coverage or a point-to-point link, compare the requirement with directional products before using an omni antenna. Confirm frequency plan, connector, mounting hardware and site wind exposure before ordering.
