460-470 MHz omnidirectional base antenna

The Laird Technologies FG4603 is a fiberglass base station antenna designed for the 460-470 MHz band with a 100 W power rating. It uses a collinear design enclosed in high-density fiberglass with a UV-inhibiting coating for extreme conditions. The radiating elements are made from high-efficiency copper and phased for maximum horizontal-plane gain. The antenna provides 5.15 dBi gain with vertical polarization and DC ground lightning protection.

N female connector and cold mounting sleeve

The antenna terminates in an N female RF connector and includes a tuned mounting sleeve that eliminates RF currents on the transmission line. This cold sleeve allows greater freedom in mounting without affecting the radiation pattern. The unit measures 44 in in length and weighs 4 lb, rated for wind velocities up to 125 mile/h. No jumper cable or additional mounting hardware is included in the package.

Suited for fixed base station deployments

This antenna suits installations requiring a durable omnidirectional radiator in the 460-470 MHz range with moderate gain and high power handling. It is not intended for mobile or portable use where a shorter whip or magnetic-mount antenna would be more practical. Buyers needing a different frequency band, higher gain, or an included feed line and mounting kit should consider alternative models.

Questions about this item

How do I confirm the FG4603 is performing correctly after installation?

Measure VSWR at the N Female connector; a reading at or below 2.0:1 across 460-470 MHz indicates proper operation.

What hardware comes with the FG4603 and what must be sourced separately?

The antenna includes only the fiberglass radome with N Female feed; mounting hardware, coaxial jumper and lightning ground kit are not supplied.

Which FG4603 variant matches a 460-470 MHz system needing 3 dBd gain?

The single FG4603 model covers 460-470 MHz with 3 dBd gain, 100 W power rating and DC ground lightning protection.
