GL-DY150Q9A 144-174 MHz 6-9 dBi Folded Dipole Antenna

High-Gain Dipole Curtain

The GL-DY150Q9A is a four-dipole panel array for 144-174 MHz, a 5.0 m by 0.9 m curtain that delivers the highest gain in this pole-mounted family at 6-9 dBi, with a 300 W power rating. Four stacked dipoles produce a focused, shaped pattern ideal for covering a defined service area from a fixed site at high power, while the panel construction keeps the array mechanically stiff and pattern-stable.

What the Four-Dipole Aperture Delivers

Four dipoles in a panel meaningfully compress the vertical beam and add gain toward the horizon, extending coverage across the served area. The gain climbs toward 9 dBi at the upper part of the band, and the broad aperture maintains a clean, predictable pattern that avoids the deep nulls a poorly designed stack can produce. The 300 W rating supports high-power transmitter and base-station duty, and vertical polarization matches land-mobile and paging networks across the 144-174 MHz range.

Pole-Mounted Design

The array fixes to an installer-supplied main pole using JM-DB clamp hardware, so it integrates with the site mast rather than relying on its own full-height support. The 50 ohm feed is available with an N-female or 7/16 DIN female connector, the DIN option preferred where high power and low intermodulation are required, and a 60 m/s wind rating supports permanent exposed installation.

Applications

• High-power VHF base and transmitter stations
• Shaped area coverage from a fixed high site
• Paging, dispatch and trunked networks on 144-174 MHz
• Pole-mounted curtain installations on existing masts

Choosing the Panel

Select GL-DY150Q9A for the most gain in the pole-mounted dipole panel family. The two-dipole GL-DY150Q6A and single-dipole GL-DY150Q3A are smaller, lower-gain options, and the GL-DY015Q9A is a closely related four-dipole panel. The supporting pole is installer-supplied; confirm the connector and JM-DB clamp arrangement before ordering.
