ADS-B and FLARM transceivers used in drones have relatively low RF transmitting power. Efficient tracking of such objects requires the design of highly sensitive receivers. The antenna technology is helpful in this case, which allows for a significant improvement of input sensitivity. Sector antennas allow increasing the operating range of ADS-B/FLARM signals in selected directions several times. This product is easily networkable using Ethernet/PoE or LTE connectivity and is optimized to work in harsh environments. Apart from drone technology, the antenna can be used for manned traffic surveillance as well.
