Shipped in a compact storage and transport box, the antenna can be assembled by one person in 30 minutes, without special tools. RELATED PRODUCTS:  DF-A0038 (Direction finding antenna with integrated monitoring system)  MISC-A0067 (Weatherproof carry case for DF elements) The full-size elements on all bands give excellent DF sensitivity. Ultimate angular resolution for strong signals is well under 1º for most of the frequency range. Dipole elements provide good cross-polarisation rejection, and fair performance for signals arriving from up to 15º above or below the horizon. This DF antenna is designed to be used with a 5-channel phasesensitive receiver, and correlative algorithm. Calibration of the antenna can be performed on request. ELECTRICAL FEATURES:  Full-size DF  Wideband DF  5-element interferometer MECHANICAL FEATURES:  Robust construction  Waterproof  Quick assembly www.alarisantennas.com Alaris Antennas has a policy of continuous improvement and hence sp

5-Element Direction Finding Antenna 20 – 3600 MHz Product Code: DF-A0001 and DF-A0007 DF sensitivity graph: Measured sensitivity of DF-A0001, IFBW=1.25kHz, RMS=1.5o/1o Field strength required [ V/m] The graph illustrates the direction finding sensitivity of a typical system measured under specific electrical conditions. The sensitivity is measured using an IF bandwidth of 1.25 kHz and without averaging. The graph shows the minimum signal required to obtain a bearing fluctuation of less than 1º for the frequency range 20 to 280 MHz and less than 1º for the frequency range 280 to 3600 MHz....
