DF-A0100 is single-band array for high precision 100-500 MHz direction finding employing a 5-channel phase-sensitive receiver/correlative algorithm.
The antenna features hardening against lightning-induced surges with an optional lightning conductor attachment for added protection. Alternately, an optional omni-directional monitoring antenna attachment can be used to provide a monitoring channel.
The full-size elements give excellent DF sensitivity. Ultimate angular resolution for strong signals is well under 1 degree RMS. Dipole elements provide good cross-polarization rejection, and fair performance for signals arriving from above or below the horizon.
