September, 2001 Array Solutions – Sunnyvale Texas, USA
Array Solutions and Custom Metal Works have provided the US Army 3rd
Special Forces Group, Ft Bragg, NC. with a radical new concept in HF communications.
This system utilizes three log periodic antennas mounted on a single large tower, which
are independently rotatable around the tower, as well as being able to be switched in
and out of phase. Using the Array Solutions’ "StackMatch technology," these antennas can
be phased together in such a way as to "steer" the take-off angle of the array. Multiple
radios can also be simultaneously used with this system, giving them the ultimate in
flexibility.
Array Solutions worked with the Army closely to design,
manufacture, and erect this system to meet their requirements of long haul, medium haul,
and short haul highly reliable HF communications. The completed system also included
phased long wire arrays, NVIS antenna arrays.
Custom Metal Works were the professional riggers for this job.
Paul Nyland, president of CMW prefabricated and installed the tower and antennas with
Array Solutions.
Jay Terleski, president of Array Solutions, comments, "This was a highly
sophisticated project that we developed for the Special Forces. They understood from
their use of ICEPAK and other propagation software programs that they needed to match
the take-off angles required for these shots. We developed the system of phased logs to
allow them to steer and match the take-off angles required with a controller system
located in the communications station. The ability to easily change the take-off angles
has already proved itself by increasing the reliability of their communications
substantially. We also delivered a complete software simulation model of this system to
investigate the possibilities of this system, as well as giving them a tool to utilize
in planning their communication shots."
Mr. Terleski added, "With this very successful benchmark system under our belts, we
are now offering this technology to commercial, marine, and military customers who
require very reliable worldwide HF communications. We are able to deliver antennas,
towers, switching and phasing equipment, and full turnkey installation worldwide."
