Yagi Antenna Role
GL400B is a 400-480 MHz Yagi Antenna for outdoor UHF links requiring a 12 dBi directional antenna. Its source record lists 12 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 or Horizontal polarization, 50 Ω nominal impedance and <=1.5 VSWR. The documented power rating is 100 W, and the published size is 1.5 m. Confirm cable loss, mating connector and mounting hardware before installation.
Installation Notes
Use GL400B where the 400-480 MHz range, 12 dBi gain and N female interface fit the point-to-point design. 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
- Directional UHF fixed-site 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 GL400B?
Confirm the operating channels, requested connector, installation method and whether the documented 1.5 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.
