GL-DYJ350BFG-Y 351-366 MHz 5 dBi Panel Antenna

Overview

The GL-DYJ350BFG-Y is a compact outdoor directional panel antenna tuned for the 351-366 MHz UHF segment used by trunked radio, professional mobile radio and narrowband data networks. Instead of spreading power in every direction like an omni mast, this flat panel concentrates its 5 dBi of gain into a forward beam, so a single unit can push usable signal down a road, along a quay or into a coverage shadow that an omnidirectional site cannot reach cleanly.

RF Performance

The antenna is matched across 351-366 MHz with a vertical polarization that aligns with the mobiles and portables typically used on this band. The 50 ohm feed terminates in an N-female connector, keeping insertion loss low and letting the panel drop straight onto standard LMR-400 or half-inch feeder. Rated input power is 50 W, which suits repeater downlinks, talk-around fill cells and low-to-medium power data links. Because the directional pattern suppresses energy toward the rear, the panel also reduces co-channel interference between neighbouring sites compared with an omni at the same height.

Construction and Mounting

At roughly 320 x 200 x 70 mm the radome is small enough to mount discreetly yet rigid enough to survive a fixed outdoor install. It is designed for vertical pole mounting, so it bolts to a mast or wall standoff with the radiating face pointed at the target coverage area. The sealed enclosure withstands sustained wind loading and year-round weather exposure on a rooftop or tower leg.

Typical Applications

• Sector and gap-fill coverage for 350 MHz trunked and conventional radio
• Directing signal along highways, tunnels approaches, ports and rail corridors
• Point-to-area links for SCADA, telemetry and dispatch backhaul
• Replacing an omni where a clean front-to-back ratio is needed to cut interference

Selection Notes

When specifying GL-DYJ350BFG-Y, confirm that your operating channels fall inside 351-366 MHz, that the planned transmit power stays within 50 W, and that the mounting pole allows the panel to be aimed and down-tilted toward the served area. For installations that need indoor wall placement or a slightly wider band, review the related GL-DYJ350BFG and GL-DYJ350BKB panels in the same family.
