Field-proven magnetic base Antennas with strong holding force

June 29, 2022/in News, Blogs /by Jenny Heyes

COJOT’s omnidirectional mag-mount antennas are the preferred choice for applications and circumstances where permanent installations are not possible and a rapid deployment and removal is preferred or even required. We provide a wide range of antennas covering VHF, UHF, GSM, LTE, 5G, WiFi and other bands. Each antenna features a strong, rugged magnet base for…

COJOT beam steering antennas with support for dual-polarized MIMO

April 28, 2022/in News, Blogs /by Jenny Heyes

COJOT supplies Switched Beam Antennas (SBAs) for different frequency bands with support for MIMO (multiple input multiple output) – featuring dual RF inputs/outputs that are connected to a different polarization of the radiator elements. MIMO is an essential requirement as modern Radio Systems are often relying on this to enhance the capacity or coverage of…
