The LPH-89I provides excellent reliability in medium to long range HF circuits. The rotatable antenna allows high power communications between a fixed station and mobile station, such as ships, aircraft or tactical deployments. The LPH-89 is a heavy weight rotatable log periodic antenna which has unique six-way guying that gives the twin towers added rigidity in hurricane force winds. A base mounted balun matches the 200 ohm antenna to the customer’s 3 1/8″ EIA, 50 ohm input. The antenna is produced to US Air Force and Navy standards. The alumoweld strand radiating array is completely factory preassembled with well rounded swaged fittings enhancing reliability and high power capability. The top mounted rotator can seek, at .4 RPM, any selected azimuth allowing for rapid acquistion of a mobile communications target. The three support booms are constructed of 6061-T6 aluminum for high strength, low weight and good corrosion resistance.
Equipment supplied includes the radiation array, support booms, rotator, twin towers, guys, feedline, balun and remote control box. Available optional equipment includes obstruction lights, climbing devices, electric erection winch, erection kit and computer controller interface.
