The Directional Antennas of the HyperLOG® series 3000 are based on an ultra-thin, GOLD COATED high tech TEFLON substrate. Based on this innovative construction, the frequency range could yet again be vastly extended compared to the 4000 antenna series. The lower frequency range now reaches down to 380MHz, thus covering, for example, the important TETRA band (380MHz and up). The extended upper-frequency range up to 18GHz now also allow the measurement of unusable signal sources like military radar, various satellite services, and more. Combined with a spectrum analyzer, an incredible EMC measurement system for mobile or laboratory use is formed, at an affordable price. As an option, the antenna calibration data can even be stored on a special IC on the antenna and be queried with our spectrum analyser series at any later time.
