The Antenna Technologies Limited Company direction finding antenna is a rugged, compact mast mounted array of VHF and UHF elements, assembled and networked to perform direction finding operations. This antenna consists of a dual array of Vivaldi elements (8 per array) operating at UHF frequencies and vertical dipole elements (8) operating at VHF frequencies. Embedded in this antenna are the electronics packages that contain the VHF and UHF beamformers, a calibration capability, and a Digital Magnetic Compass. Each array provides Omni, Sine, and Cosine outputs that can be utilized for accurate direction finding.
