TYPE 183 1.8M CLASS III TXRX ANTENNA

Polarization: Linear Cross Pol, Tx Operating Frequency: 13.75 - 14.5 GHz, Rx Operating Frequency: 10.95 - 12.75 GHz, Includes: Fiberglass reflector, az/el mount with fine azimuth, and elevation adjustment, feed support with transmit feed horn, Orthomode Transducer (OMT) and Transmit-Reject Filter (TRF) assembly, 4.5" OD ( 114mm) Mast Pipe interface, Intelsat Approved. (62-1835611)

The Skyware Global Type 183 1.8 m Class III Tx/Rx Antenna is a rugged commercial grade product suitable for the most demanding applications. The reflector is thermoset-molded for strength and surface accuracy. Molded into the rear of the reflector is a network of support ribs which not only strengthens the antenna, but also helps to sustain the critical parabolic shape necessary for transmit performance.

The Az/El mount is constructed from heavy-gauge steel to provide a rigid support to the reflector and feed support arm. Heavy-duty lockdown bolts secure the mount to any 4.50" (114 mm) O.D. mast and prevent slippage in high winds. Hot-dip galvanizing is standard for maximum environmental protection.

TYPE 183 FEATURES

  • One-piece precision offset thermoset-molded reflector.
  • Fine azimuth and elevation adjustments.
  • Galvanized feed support arms and alignment struts.
  • Factory pre-assembled mount.
  • Galvanized and stainless hardware for maximum corrosion resistance.
  • Heavy-duty Class III mount for 25 lb (11 kg) RF electronics (LNB & BUC).
