Direction Finding & Monitoring Antenna


This direction finding and monitoring antenna covers a frequency range of 20 MHz to 410 MHz. Shipped in a compact storage and transport box, the antenna can be assembled by one person in 20 minutes, without special tools. The full-size elements give excellent DF sensitivity. Ultimate angular resolution for strong signals is well under 1° for most of the frequency range. Dipole elements provide good crosspolarisation rejection, and fair performance for signals arriving from up to 15° above or below the horizon. 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
