The unit is used in ground based EW application for direction finding. It is mounted on a ~15 meter retractable mast. It receives a frequency band from 0.5 GHz to 18 GHz. To receive this wide band frequency and to have coverage of 360 degree, an irregular Octagon mechanical shell is designed to fit 12 No’s of antennas in a single system.
