Spring-equipped mobile configuration

GL350DII is a 120 cm mobile antenna for 330-390 MHz systems. It combines 5.5 dBi gain with a UHF male connector, M110 magnetic-mount compatibility and a bottom spring described by the source as protection against collision.

RF limits

The documented values are 100 W maximum input power, vertical polarization, 50 Ω nominal impedance and ≤1.2 VSWR. The lower listed VSWR value should be considered together with the installed mount, cable and vehicle ground plane, since final system performance depends on the complete assembly.

Deployment use

This model is intended for vehicles, service radios and temporary UHF systems working in the stated band. Check rooftop clearance, mount retention, cable strain relief and vehicle-specific ground-plane conditions before commissioning.

Selection question

Select GL350DII when the 330-390 MHz range, 120 cm length and spring-equipped M110-compatible configuration fit the use case. State whether the quote must include any mounting hardware or only the antenna.

Typical Applications

UHF vehicle mobile antenna
System integration with a specified 50 Ω feed line
Projects that document frequency, connector and mounting details before ordering

Questions Before Ordering

What distinguishes GL350DII from GL350DI?

GL350DII is specified for 330-390 MHz with ≤1.2 VSWR and a bottom spring; GL350DI covers 300-390 MHz.

What connector is used?

The source lists a UHF male connector.
