This is a reference guide for the erection and recovery of the HF antenna system NSN: 5985-01-455-
9286. It may be used in lieu of contractors Technical Manual TM-1099, TM-H2270/2 and EL1142A
which came with the antenna system.

PLANNING THE ANTENNA ERECTION
Consideration must be given to the impact that terrain has, i.e. vegetation, obstacles, and other
circumstances, may have on the antenna deployment. Divide the tasks necessary to complete the job
as evenly as possible between personnel available. A crew of two is the minimum number of persons
required to perform this task safely. To avoid unnecessary lengthy trips to the far ends of the
deployed antenna, plan ahead so that you arrive there with all the equipment and supplies you need
to terminate and tension the element wires. Decide on the location for the antenna mast. Ensure you
have sufficient coaxial cable to reach the mast base from the radio.
The antenna and radio is designed to operate with the
provided coaxial cables. The total run of cable should
not exceed 150 feet from the balun to the radio.
The broadband Fan Configuration is omni directional up to about 750-1,000 miles. However, better low
angle performance for greater ranges will be obtained when the distant station is about 90 degrees off
the long axis of the antenna i.e.; more or less in line with the outside elements of the antenna.
