Product catalog summary
Overview: The HD65 Series Antenna Pedestal is designed for high reliability and accuracy in supporting solid reflectors up to 4.5 meters and FLAPS™ reflectors up to 5.5 meters in winds of 50 MPH. It features EL/AZ or X-Y positioner configurations, auto-tracking feed, and supports L-Band through Ka-Band frequencies.
Key Features:
  • High torque and low backlash achieved through planocentric gearboxes and brushless DC motors.
  • Rotary joints and sliprings for continuous azimuth rotation.
  • PC-based automated control with P-Series ACU.
  • Optional features include acquisition-aid antenna, compass, inclinometer, and fiber-optic control.
Specifications:
  • Reflector Diameter: 3.0 to 4.5 meters for solid reflectors, up to 5.5 meters for FLAPS™.
  • Operating Frequency: 1435 MHz to 2400 MHz, with other bands available upon request.
  • Polarization: Simultaneous right and left-hand circular, with orthogonal linear polarizations available.
  • VSWR: Maximum of 2.0:1.
  • Environmental Conditions: Operates in temperatures from -20°C to +52°C, with storage temperatures from -54°C to +71°C. Can withstand winds up to 80 km/h, gusting to 105 km/h.
  • Power Requirements: 110-220 VAC, 50-60 Hz, single phase.
Performance:
  • Antenna Gain: Ranges from 29.5 dBi to 37.5 dBi depending on frequency.
  • Beamwidth: Varies from 4.6° to 1.8°.
  • Torque: Continuous torque of 3,600 ft-lbs and peak torque of 7,200 ft-lbs.
  • Travel: Azimuth travel of 420° minimum with cable wrap, 360° continuous with slipring.
Additional Information: The HD65 is equipped with safety switches, modular components, and strategically placed access hatches for easy maintenance. It is approved for public release by DOD/OSR 11-S-3181.
