DESCRIPTION

The SPA 001 is a high performance shorted patch antenna intended for applications in the 902-928 MHz Spread Spectrum band. Fully metalized ground plane on the backside permits attachment to a variety of surfaces without significant effect on the resonant frequency or the directional pattern.

Each assembly is 100% tested for conformance to the MIN./MAX. specification limits at 25°C.

FEATURES

Low VSWR, 1.2:1 Typical

Compact, rugged packaging

Connectorized for ease of installation.
