Product Description

The 647 utilizes two DF arrays and a biconical omnidirectional monitoring / reference antenna. The DF arrays consist of nine fan elements housed in a low-loss radome. The radome encloses a broadband RF switch which 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.
