DF-A0120 is a wideband DF antenna for on-the-move direction finding from 20 to 3000 MHz. Rugged and compact, the antenna system easily transitions from mounted to dismounted use.
The antenna array is implemented as a dual-band vertical stack. Low frequency performance is improved sensitivity versus traditional designs of the same size by patented hybrid loop-Adcock technology. Antenna patterns suitable for the Watson Watt estimation method, as well as 3-channel correlative DF are produced by the arrays. Band switching is done via an integrated switch and control system. External and internal RF chain calibration is accommodated. The unit also contains an electronic compass and active GPS antenna.
Spring-mounting is accomplished via the base-mounted MIL-DTL-38999 connector interface. An optional isolating extension mast is also available for use on vehicles or marine platforms.
