Innovative Smart Antennas enhance RF capabilities

February 17, 2021/in News /by Norbert Nawroth

COJOT Switched Beam Antennas (SBAs) are innovative smart antennas that provide beam steering functionality i.e.; enabling to steer beams with a heightened sensitivity and gain to a particular or multiple directions. With their ability for extremely fast beam switching, our SBAs provide improved performance and enhanced capabilities to RF-Systems used in applications such as: Counter-Unmanned…

COJOT INCREASES SPEED OF TEST MEASUREMENT

February 15, 2021/in News /by Norbert Nawroth

In striving for service excellence, COJOT continuously looks for new or improved ways of working. Recently, we introduced new software in our anechoic chamber to improve our measurement and testing procedures. We are now able to measure the products through their operating bands about 60-70 times faster. In addition to the shorter measurement time, the…
