Overview

The GL-DYC350DII is a UHF mobile antenna for 330-390 MHz UHF land-mobile, utility and field-service radio installations. It gives installers a vertical whip-style radiator for vehicles, temporary radio kits and field test platforms where a fixed fiberglass base antenna would be too large or too permanent.

RF Performance

The source specification lists 330-390 MHz, 5.5 dBi gain and 100 W maximum input power. VSWR is listed as <=1.2(Center frequency), nominal impedance is 50 Ω, and the feed detail is UHF Male connector. This combination suits practical mobile radio coverage, dispatch support, service vehicles and temporary RF checks inside the stated band.

Build and Installation

Mechanically, the antenna uses a 120 cm vertical profile, 220 g weight and vertical polarization. The product notes specify: Bottom spring which can prevent collision. Matches with M110 magnetic mount. The spring base helps protect the whip from low-speed knocks, branches and workshop handling during mobile service. It is intended to work with a M110 magnetic mount, so the roof, bracket or test platform should provide a suitable metal ground plane and a protected cable route. The UHF Male feed keeps the installation straightforward when the vehicle cable assembly uses the same interface.

Typical Applications

Vehicle-mounted UHF radio systems for service, utility and maintenance teams
Temporary field communications kits that need a removable magnetic-mount antenna
Emergency support vehicles, site surveys and RF test platforms
Fleet or facility radio systems that need a replaceable mobile whip matched to the operating band

Selection Notes

Choose GL-DYC350DII when the radio plan matches 330-390 MHz and a mobile antenna is preferred over a fixed mast antenna. Confirm the exact operating channel, required connector, magnetic mount, cable length, vehicle surface, ground plane and height clearance before ordering or commissioning the installation.
