The GL-DYJ230B is a vertical fiberglass omnidirectional antenna specified for 220-290 MHz. It provides a fixed-site radiator for mast, rooftop and outdoor radio installations that need horizontal 360-degree coverage around the antenna. The source document lists 6.5 dBi gain, 100 W maximum input power and a SL16 female or customization connection.
The documented electrical values are 220-290 MHz, 6.5 dBi gain, <=1.5 VSWR, 50 Ω nominal impedance and vertical polarization. The listed vertical beamwidth is 25°. These figures should be matched to the operating channels and coverage objective before procurement. The antenna should be installed vertically and positioned away from nearby metalwork that could distort the intended pattern.
The fiberglass construction is intended for fixed outdoor deployment. The source lists a length of 2.5 m, weight of 2.5 kg, and a rated wind velocity of 60 m/s. The connector is SL16 female or customization. The source remarks state: Fiberglass. Mounting hardware, support pole diameter, cable type, lightning protection and grounding should be confirmed for the final site.
Choose the GL-DYJ230B when the operating band, gain, power rating, connector and physical length all fit the system design. Verify the final mounting bracket, feed-line loss, tower loading, grounding, lightning protection and local wind conditions. For multi-segment frequency listings, state the exact required operating segment in the quotation request so the supplied configuration can be confirmed.
