The LPH-89 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 military nomenclatured as AS-3482/GRC, and 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,
rotaotr, 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. |
