Additional Product Info

The LPH-1 antenna is a light weight, high strength rotatable log periodic antenna which provides excellent HF performance in the 6.2 to 30 Mhz band. The antenna provides excellent reliability in medium to long range HF circuits. It allows high power communications between a fixed station and mobile station, such as ships, aircraft or tactical deployments. A rotary joint allows continuous rotation. The antenna (Mil Type AS-3520/F) is produced to US Air Force requirements and is suitable for use where limited space and difficult access are encountered. The antenna system is supplied with a 60 foot tall tower. Primarily constructed of aluminum with the longest single piece being 12 feet, the entire system can easily be roof mounted. A 60 foot tall self supporting tower is also available. The rotator is controlled remotely to any azimuth, with lights indicating the antenna heading. Equipment supplied includes the radiation array, support booms, rotator, tower, guys, feedline, balun and remote control box. Available optional equipment includes tower heights from 24 to 60 feet, obstruction lights, erection winch, erection kit, RS 232 computer controller interface, coaxial cable, connetor adapters, and mating adapters.
