            ANTENNA PRODUCTS CORPORATION LPH-1

            GENERAL DESCRIPTION


            LIGHTWEIGHT, ROTATABLE, HORIZONTAL POLARIZATION, MIL TYPE AS-3250/F - LPH-1

            photo Antenna Products Corporation LPH-1 Applications

            The LPH-1 provides excellent reliability in medium to long range HF circuits. The rotatable antenna allows communication between a fixed station and mobile station, such as ships, aircraft, or tactical deployments.

            Features

            The LPH-1 rotatable log periodic array (RLPA) is a lightweight, high strength antenna which provides excellent HF performance in the 6.2 to 30 MHz frequency band. A rotary joint allows continuous rotation.

            Characteristics

            The LPH-1 (Military Type AS-3520/F) lightweight, rotatable, horizontal log periodic antenna, produced to U.S. Air Force requirements, is suitable for use where limited space and difficult access are encountered. The LPH-1 ssystem is supplied with a 60-foot tower. Primarily constructed of aluminium with the longest single piece being twelve feet, the entire system can easily be roof-mounted. A sixty foot self-supporting tower is also available. The rotator is controlled remotely to any azimuth, with lights indicating the antenna heading.

            Equipment Supplied

            Array, balun transformer, rotator, sixty-foot guyed tower, and remote control unit.

            Optional Equipment

            Tower from 24 to 60 feet (12-foot increments), erection kit, erection winch, and obstruction lights. Coaxial cable, connector adapters and mating adapters. Computer controller with RS-232 interface.
