Mobile Antenna Role
GL400BII is a 400-480 MHz Mobile Antenna for vehicle UHF installations that benefit from a bottom spring and M90 magnetic mount. Its source record lists 3.5 dBi gain, UHF Male connector and M90 magnetic 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 . Confirm cable loss, mating connector and mounting hardware before installation.
Installation Notes
Use GL400BII where the installation needs a 50 cm whip, UHF male connector and collision-resistant bottom spring. 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
- UHF vehicle mobile 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 GL400BII?
Confirm the operating channels, requested connector, installation method and whether the documented 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.
