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.

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.
