LPH-1A
2-30 MHz RLPA |
|
The LPH-1A antenna is a light weight, high
strength rotatable log periodic antenna which provides excellent
HF performance in the 2 to 30 Mhz band. The antenna is an extended
frequency range version of the LPH-1 and 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 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. |
