Fiberglass Omni Antenna Role

GL400D is a 400-480 MHz Fiberglass Omni Antenna for large outdoor UHF sites that can support a two-part high-gain fiberglass antenna. Its source record lists 10.2 dBi gain, N Female or Customization connector and Outdoor pole 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 100 W, and the published size is 4.0 m. Confirm cable loss, mating connector and mounting hardware before installation.

Installation Notes

Use GL400D where the 10.2 dBi gain, 4.0 m two-part construction and N female interface fit the tower 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-gain UHF fixed-site omnidirectional antenna
Systems that operate inside 400-480 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 GL400D?

Confirm the operating channels, requested connector, installation method and whether the documented 4.0 m 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.
