Description

The DF-A0148 is a wideband Watson Watt DF antenna intended for on-the-move direction finding from 20 to 3000 MHz.

The antenna array is implemented as a dual-band vertical stack with the low frequency band enhanced with patented hybrid loop-Adcock technology to provide improved sensitivity vs traditional designs of the same form factor.

The antenna presents patterns suitable for the Watson Watt estimation method, as well as 3-channel correlative Direction Finding. Band switching is done via an integrated switch and control system. External and internal RF chain calibration is accommodated and a compass and active GPS antenna are also integrated in the antenna.

For improved electrical performance in the 20 to 300 MHz frequency band an optional VHF module DF-A0148-VHF) is available. The module also makes use of the Alaris Antennas patented hybrid loop technology and takes advantage of the increased dimensions to improve the sensitivity when compared to the DF-A0148 Band B array.

Mounting is directly via the base-mounted MIL DTL 38999 connector interface. An optional spring mounted isolating extension mast is also available for use on vehicles or marine platforms. This provides improved performance over simply mounting the antenna directly to the structures.
