Tall high-gain UHF radiator

GL350C is a 10.2 dBi fiberglass omni antenna for 300-390 MHz installations that can accommodate a 4.7 m radiator. Its 10° vertical beamwidth is much tighter than the lower-gain models, making antenna height and site geometry especially important to the final coverage result.

Two-part mechanical planning

The source states that the fiberglass construction is separated into two parts. It weighs 4.5 kg, is rated for 100 W input power and 60 m/s wind velocity, and uses an SL16 female or customized connector. Plan shipping, assembly, mast loading and cable support before installation.

Deployment use

Consider GL350C for established UHF base sites, remote infrastructure and coverage systems that need high gain across 300-390 MHz. The high-gain pattern should be evaluated against terrain, near-site users and the desired service elevation before selecting it.

Selection question

Choose GL350C when the site can support the two-part 4.7 m construction and the coverage plan benefits from 10.2 dBi gain. Specify any non-standard connector in the quotation request.

Typical Applications

High-gain UHF fixed-site omnidirectional antenna
System integration with a specified 50 Ω feed line
Projects that document frequency, connector and mounting details before ordering

Questions Before Ordering

Is GL350C supplied in one piece?

No. The source notes that the fiberglass antenna is separated into two parts.

Why is site height important?

Its listed 10° vertical beamwidth makes mast height and terrain more influential than with a lower-gain omni model.
