Dual-Band Fiberglass Antenna

The Laird Technologies Antenex FG821/18503 is a dual-band fiberglass omnidirectional antenna designed for base station and micro base station deployments. It serves public safety agencies, commercial organisations and military users requiring reliable land-based or marine radio and data transmissions across two cellular bands. The gold anodised sleeve and N Female connector provide a durable, professional-grade connection point for fixed-site installations.

Operating Bands and Construction

This antenna operates across the 806-896 MHz and 1850-1990 MHz frequency ranges, covering dual-band cellular and PCS spectrum in a single vertical element. The fiberglass radome protects the internal radiating elements from weather and marine environments while the gold anodised sleeve resists corrosion. The focused beam pattern delivers high gain and efficiency for extended coverage in repeater or direct-connect scenarios.

Integrated Connector and Mounting

The factory-fitted N Female (Jack) connector allows direct attachment to low-loss coaxial cable runs without adapters, preserving signal integrity across both operating bands. The rugged fiberglass housing and anodised sleeve eliminate the need for additional weatherproofing kits in most fixed or marine mounting situations. No software or active components are included; the antenna is a passive RF device ready for immediate integration with compatible repeaters, amplifiers or cellular terminals.

Questions about this item

How do I mount the FG821/18503 on a mast and which connector do I use?

The antenna has an N Female jack on the gold anodized sleeve; attach a low-loss coaxial cable with an N Male plug and secure the fiberglass radome to a vertical mast using U-bolts or a mounting bracket, ensuring the radiator remains clear of metal objects.

What part of the FG821/18503 is most likely to need replacement after long-term outdoor exposure?

The fiberglass radome and gold anodized sleeve resist UV and corrosion, but the N Female connector can accumulate moisture; inspect the connector seal annually and replace the coaxial jumper if the centre pin shows oxidation.

At what frequency does the FG821/18503 gain roll off first during continuous high-power transmission?

Gain is specified across 806-896 MHz and 1850-1990 MHz; sustained high power near the band edges can raise the feed-point temperature, causing VSWR to degrade first at the upper 1850-1990 MHz range before the lower band.
