UHF Interferometer
DF-A0100
The DF-A0100 is single band 100 to 500 MHz antenna array for use in high precision DF applications. The antenna features hardening against lightning-induced surges with an optional lightning conductor attachment available for added protection. Alternately, an optional omni-directional monitoring antenna attachment can be used to provide an additional monitoring channel. The full-size elements give excellent DF sensitivity. Ultimate angular resolution for strong signals is well under 1°. Dipole elements provide good crosspolarisation rejection, and fair performance for signals arriving from above or below the horison. This DF antenna is designed to be used with a 5- channel phase-sensitive receiver, and correlative algorithm. Calibration of the antenna can be performed on request.
