A variety of wideband omnidirectional antennas from COJOT for manpacks and vehicles cover 20 - 6000 MHz for communications, countermeasures and monitoring applications. Dozens of models are available, some requiring a groundplane, others ground plane independent. Below is a sampling of these rugged and well-performing antennas.
These high gain omnidirectional antennas use co-linear design with integrated balun, making them groundplane independent and suitable for use on many platforms, such as manpacks and mobile electronics. The radiator is in the top half of the radome to mitigate HERP. Designed for use in extreme operational environments.
