Overview

The GL-DY150D is a rugged VHF omni with aluminum-alloy construction for fixed 134-173 MHz service where a compact 1.5 m antenna and 3.7 dBi gain are preferred. It gives system designers a clean vertical omni pattern for fixed RF coverage where the signal must serve users around the site rather than only in one direction.

RF Performance

Its core RF specification is 134-173 MHz, 3.7 dBi gain, 100 W maximum input power and UHF female connection. Bandwidth is listed as 8 MHz, VSWR as <= 1.5, and the feed is 50 ohm, making it suitable for conventional base-station, repeater and monitoring equipment.

Build and Installation

The antenna uses a 1.5 m outdoor structure with vertical polarization and a 60 m / s wind rating. The source notes identify the construction as Aluminum alloy, so the listing keeps the mechanical claim tied to the original product data rather than adding unsupported material claims.

Typical Applications

VHF 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-DY150D when the site needs an omnidirectional VHF or private-radio antenna 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.
