GL400DQ 380-470 MHz 8.15-11.15 dBi 4 Folded Dipole Antenna

4 Folded Dipole Antenna Role

GL400DQ is a 380-470 MHz 4 Folded Dipole Antenna for base-station systems that need a four-element folded-dipole array with adjustable coverage gain. Its source record lists 8.15-11.15 dBi gain, N Female or 7/16DIN connector and Customer-supplied mast mount, so the product page is kept tied to those exact ordering details.

RF and Mechanical Fit

The antenna uses Vertical polarization, 50 Ω nominal impedance and <=1.5 VSWR. The documented power rating is 300 W, and the published size is 273 cm. Confirm cable loss, mating connector and mounting hardware before installation.

Installation Notes

Use GL400DQ where the 380-470 MHz range, 300 W rating and 2.73 m array fit the tower and coverage plan. Do not substitute a similar GL-DY or adjacent Evelyn model unless the frequency range, connector, mounting method and mechanical envelope have all been checked against the project requirement.

Application Fit

• High-power UHF base-station antenna
• Systems that operate inside 380-470 MHz and require a 50 Ω antenna path
• OEM or project builds where the SKU, connector and mounting details are stated before quotation

Selection Questions

What should be confirmed before ordering GL400DQ?

Confirm the operating channels, requested connector, installation method and whether the documented 273 cm size is acceptable for the equipment or support structure.

Can this model be swapped with a nearby SKU?

Only after engineering review. Several Evelyn models share a similar frequency family but differ by suffix, connector, power rating, gain, mount or physical length.
