GL-DYJ350BFG 350-370 MHz 5 dBi Panel Antenna

What It Is

The GL-DYJ350BFG is the indoor wall-mount member of the 350 MHz directional panel family. It covers 350-370 MHz, a span widely used by in-building professional radio, security teams and site-wide dispatch systems, and delivers 5 dBi of forward gain from a flat housing that sits flush against a wall. The goal is simple: take the signal from a base station or distributed antenna run and project it cleanly across one indoor zone rather than wasting it into the structure behind the panel.

Coverage Behaviour

Mounted on a wall with the radiating face looking into the room, the panel illuminates a hall, atrium, warehouse aisle or parking deck with a controlled directional pattern. Its vertical polarization matches handheld portables, and the rearward null helps keep RF out of adjacent areas and off the floor above or below, which is useful when several panels share a building and must not overlap noisily. The 50 ohm N-female port handles up to 50 W and connects directly to coaxial risers or a combiner.

Mechanical Design

The enclosure measures about 320 x 200 x 70 mm, slim enough to look at home in finished interiors while remaining tough enough for back-of-house plant rooms and loading bays. Fixing points are arranged for straightforward vertical wall mounting, and the smooth radome resists dust and incidental knocks in busy operational spaces.

Where It Fits

• In-building UHF two-way radio for factories, logistics centres and campuses
• Coverage fill for stairwells, basements and large open floors
• Distributed antenna system end-points on the 350-370 MHz band
• Security and facilities dispatch where one wall panel must serve one defined area

Specifying the Antenna

Check that the in-building channels lie within 350-370 MHz and that combined power at the panel stays at or below 50 W. Plan the wall position so the beam reaches the far side of the served space, and use the outdoor pole-mount GL-DYJ350BFG-Y where the same coverage job has to be done from a mast outside.
