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.
