Product Description

The 645-8 utilises two DF arrays and a biconical omnidirectional monitoring / reference antenna. The DF arrays consist of nine vertically polarised fan elements housed in a low-loss radome. The radome encloses a broadband RF switch that commutates signals from the DF elements to an external multi-channel DF/Monitoring receiver and generates test signals for DF calibration and automatic system self-test. The antenna housing can be a standard hemispherical radome, or a luggage carrier mounted on a vehicle roof for covert applications.
