One person can set up the lightweight, collapsible, man-transportable, DF antenna in less than 5 minutes.

The lightweight, collapsible, man-transportable, direction-finding (DF) antenna (AP-460) designed by Southwest Research Institute (SwRI) is specifically designed for tactical field applications. The antenna elements and associated cabling are fully integrated into a collapsible "tent" structure that fits into a backpack. The antenna can be placed on any flat surface or mounted on a supplied tripod and mast. Setup and dismantling times are less than 5 minutes by a single person.

 

Features of the DF Antenna

  • 20 MHz to 3 GHz frequency coverage

  • Acquisition and DF outputs, amplified

  • Integrated cabling and sequencer

  • Less than 5-minute set-up time/dismantle time

  • Lightweight and man-transportable

  • Low cost

Advantages of Using the DF Antenna

  • The antenna elements and associated cabling are fully integrated into a collapsible "tent" structure that fits into a backpack.

  • The antenna can be placed on the ground or mounted on a supplied tripod and mast.

  • Total weight of the antenna structure is less than 5 pounds.

  • The antenna extends to a maximum height of 20 feet above the ground using the supplied tripod and mast.

  • The tripod, mast, and supporting hardware fit inside a carrying case with a total weight of less than 25 pounds for easy transportation.

  • The DF antenna provides full instantaneous coverage across three bands of operation covering 20 MHz to 3 GHz frequency spectrum.

  • The antenna may be used with a variety of narrow or wideband signals intelligence (SIGINT) systems.

  • When used with a dual-channel DF system using SwRI's beam-steer vector match (BSVM) DF algorithm, the DF antenna is capable of producing exceptional DF line-of-bearing (LOB) accuracy of less than 5° across the operating frequency range.
