COJOT Product Spotlight: Fixed Site Antennas

For temporary and permanent fixed site Systems used in Electronic Counter Measure (like C-UAV/UAS Jamming), communication and monitoring applications our broad range of wideband antennas can be an ideal choice for installation on tripods, (tactical) masts or shelters and containers – including directional, omnidirectional, sector and Switched Beam Antenna solutions.

Our well-known multi use antenna concept (available for several antenna models) even allows for a quick platform change when switching from a fixed site installation to a mobile vehicle platform, or vice versa. Consisting of a removable dipole vehicle antenna radiator (like the COJOT WD2250M-R) and a smart mounting device, called MASTMO, the antenna is easily installed onto different platforms – importantly without the need for any tools.

  • Gain: >9dBi

Switched Beam Antennas

For C-UAS detection and jamming and tactical communication networks

  • 360° coverage with long detection range
  • Different beam modes (wide and omni) configurable to “point” in single or multiple directions concurrently
  • Monitors in omni or sweep mode to automatically switch to a narrow beam for jamming or tracking operation
    • 18deg accuracy for amplitude based detection (with 20 beams)
    •  More accuracy can be achieved with added analysis
  • Low (10W) and high power (100W) antennas for various frequency ranges
