Wider mobile operating range

GL350DI covers 300-390 MHz, providing a broader documented range than the 330-390 MHz GL350CII. It is a 120 cm mobile antenna with 5.5 dBi gain for vehicle or temporary UHF installations using the stated M110 magnetic-mount arrangement.

Specified interface

The antenna uses a UHF male connector and is rated for 100 W with vertical polarization, 50 Ω impedance and ≤1.5 VSWR. At 220 g, it still requires a secure mount, appropriate ground plane and cable routing that respects the vehicle's operating environment.

Deployment use

GL350DI can be selected for fleet, service and field-radio systems whose channels remain within 300-390 MHz. Confirm the vehicle roof geometry, mast alternative if used, feeder assembly and overall height clearance before deployment.

Selection question

Choose GL350DI when the wider 300-390 MHz range and 120 cm form factor are needed. It is a mobile antenna; for a permanent rooftop site, use a product with an explicit fixed mast configuration.

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
