New Triple-Band Antenna for Counter Drone Applications

Cobham has introduced a new Triple-band Helix antenna system called C-UAS Antenna. The new Helix, model number TAMH-1.6-2.4-5.8/2453, is designed with SWaP principles – improved performance while reducing Size, Weight and Power requirement for hand-held and fixed installations.

This is achieved by housing three antennas in a single radome, covering the three most popular commercially used bands: 1.6 GHz (GPS), 2.4 GHz and 5.8 GHz. It is of particular benefit to portable systems, being lighter and easier to handle. Furthermore, for fixed installations, its SWaP efficiencies make mounting three antennas in close proximity much more straightforward. Its three-into-one configuration also reduces wind-loading. 

These benefits meet Counter-Drone System (or C-UAS; Counter-Unmanned Aerial Systems) requirements – especially important following the recent and much reported hazardous incursions into restricted airspace over airports by illegally flown commercial drones.

All three of the antennas within the radome are Helix (i.e. circular-polarised), which ensures the greatest probability of coupling with the antenna on the target drone, under most flight conditions. Each provides 13 dBiC gain and narrow, 33-degree beam-widths, which reduces the possibility of it interfering with non-hostile systems operating in the same bands.

Features offered by TAMH-1.6-2.4-5.8/2453

  • Designed for use with C-UAS Systems 
  • Three bands in a single housing, 1.6, 2.4 & 5.8 GHz 
  • High power, 25W per band 
  • Circular polarisation for all bands increases the overall effectiveness 
  • Narrow beam, 33 deg reduces interference outside the target zone

The antenna will be on display at the unmanned vehicle show, AUVSI XPONENTIAL 2019, at McCormick Place in Chicago, USA, 30 April - 1 May 2019.
