The SPRL-A0001 is a wideband LHCP cavity backed spiral antenna. It is designed for ECM, surveillance and telemetry applications, and, exhibiting low pattern re-entrance and good phase stability for the entire range of its operating band, is extremely suitable for direction finding applications of various types.

SPRL-A0001 features a low VSWR and high gain over the operating band, and has compact and lightweight package.

Operation from as low as 500 MHz to 6 GHz is possible with reduced performance. SPRL-A0001-01 provides a weatherproof radome to cover the otherwise exposed PCB radiator and is for use when the antenna is to be mounted outdoors and not in a protected system enclosure.
