We manufacture a wide range of spiral antennas for use in a multitude of applications including SIGINT, direction finding, spectrum management, Radar Warning Receivers (RWR), ESM and low-power jamming.

Our spiral antennas provide almost frequency-independent performance over wide bandwidths and with broad beam widths. Their purity of circular polarisation creates outstanding left-hand circularly polarised or right-hand circularly polarised antennas. Most of our spiral antennas are 2-arm spiral versions but our expertise also extends to the design and manufacture of 4-arm spiral versions.

Our spiral antennas are compact and lightweight, formed by placing the spiral on top of a cylindrical absorber-filled cavity. They can be used in communication applications as single elements, in arrays, or as feeds in reflectors. Where required, additional protection can be provided by covering with a lensed radome.
