RAO 2T Series antennas are designed for using as transceiving antennas in trunking multichannel systems supporting Tetra standard. The antennas can be used both as stand-alone sector antennas in telecommunication systems operating in cellular-segmented service zones and as the components of circular antenna arrays. The antennas of this type are of great demand due to enhanced gain factor. The RAO 2T antenna represents a phased array comprising two broad passband components with parallel feeding. Specific form of the reflector element provides the necessary radiation sectors (120°). The panel antennas of this class favorably differ from the classical folded dipole antenna arrays in that they have guaranteed standard width of the directional diagram, enhanced backfire suppression. Its special ABS-plastic radome provides reliable protection from solar ultraviolet radiation.
