Airport Antenna Systems

CHEVELEY, United Kingdom – This newly developed sinuous, spiral antenna is particularly suitable for security, surveillance and EW applications.   Its rugged, machined housing makes it ideal for harsh environments.

All development engineering and manufacture has been carried out in the UK which means that the product is not subject to ITAR.

Ultra wideband, frequency covers 2 to 18GHz.

Directional, the Beamwidth is 65° to 95° in azimuth and elevation, with a maximum Beam Squint of only +/-4 degrees to -3 dB points across the band. 

Dual circular (Right and Left Hand) polarisation over the entire band means that there is no likelihood of any frequency being missed at any polarisation.

The very good, consistent, monotonic radiation patterns enable Direction Find (DF) systems to provide accurate Angle of Arrival data when using amplitude comparison techniques. Amplitude-matched sets of antennas can be provided.

Phase-matched sets of antennas can be provided, with support radiation pattern data, to allow high resolution DF.

Dimensions 84mm (3.3”) by 67mm (2.6”) diameter, weight 250 grams (8.8 ounces).
