Cavity Backed Spiral Antenna

SPRL-A0027

SPRL-A0027 is a wideband left-hand/right-hand circularly polarised cavity backed 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-A0027 features a low VSWR and high gain over the operating band and has compact and lightweight package. Operation from as low as 500 MHz is possible with reduced performance SPRL-A0027-02/-03 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.
