8-Element Direction Finding Antenna


The DF-A0164 wideband direction finding antenna covers a frequency range of 80 MHz to 4 GHz. Shipped in a compact storage and transport box, the antenna can be assembled by one person in 30 minutes, without special tools The full-size elements on all bands give excellent sensitivity to incoming waves and impulses. Ultimate angular resolution for strong signals is well under 1° for most of the frequency range. Dipole elements provide good cross-polarisation rejection, and fair performance for signals arriving from up to 15° above or below the horizon. The antenna is suitable to be used for passive radar applications.
