Compact Direction Finding Antenna System
DFS-A0250
Active
The DFS-A0250 direction finding antenna system covers a frequency range of 400 MHz to 6000 GHz. The full-size elements on all bands give excellent DF sensitivity. Ultimate angular resolution for strong signals is well under 1° for most of the frequency range. Dipole elements provide good crosspolarization rejection, and fair performance for signals arriving from up to 15° above or below the horizon. This DF antenna is designed to be used either a 5- or 2-channel phase-sensitive receiver, and correlative algorithm. Characterization of the antenna can be performed on request.
