Features:
The antenna is ruggedly designed and will withstand harsh environments such as high wind, ice, and snow. The broadband frequency capability does not require tuning.
Characteristics:
The antenna is designed in accordance with the U.S. Navy specifications MIL-A-28768B (EC) and MIL-A-28768/1B (EC). The antenna is a fixed station antenna which covers various frequency bands without requiring any frequency tunings or frequency adjustments.
Equipment Supplied:
Prefabricated alumoweld curtain, galvanized steel tower with built-in ladder, safety climbing equipment, guys, base insulator, embedment hardware, ground screen, antenna matching unit, and spare hardware.
Optional Equipment:
Repair kit, repair tool kit, and erection kit. Coaxial cable, connector adapters and mating adapters.
