The DF-A0113 is a 3-element interferometer type antenna array that is suitable for on-the-march DF of signals from 1 to 88 MHz.
The DF-A0113 is a 3-element DF interferometer type antenna array that is suitable for on-the-march Direction Finding of signals from 1 to 88 MHz.
The antenna elements are dipoles fed using a balun arrangement, optimised for maximum gain in the band of relevance. The array spacing is as large as practically possible to provide for the highest possible sensitivity in the HF band. Integrated filters are provided to suppress strong emitters above 88 MHz.
The flexible rubber-coated antenna elements are quick-removable for compact stowing with the balun unit and central mounting stalk. The antenna is mounted via a quick-disconnect spring fitting to the manpack.
Output from the antenna is provided by means of a multi-RF cable assembly using a MIL-DTL-38999 standard connector providing the three output RF signals on a single connector interface.
A version of the antenna can be provided with 3-to-2 commutation capability via an integrated RF switch system. This system also provides integrated electronic compass and GPS antenna. Power, control and data are via the same shared MIL-DTL-38999 connector.
