SKYWARE GLOBAL TYPE 183 1.8-METER C-BAND ANTENNA

Frequency Range: Rx 3.625 – 4.2 GHz, Tx 5.850 – 6.425GHz, WR137 Flange Transmit Input, Includes: fiberglass reflector, az/el mount with fine azimuth, and elevation adjustment (4.5″, 114mm mast pipe interface), feed support with transmit feed horn, Orthomode Transducer (OMT) and transmit-reject filter assembly. Intelsat Approved (62-1833911L)

The Skyware Global Type 183 1.8 m Class III RxTx 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 each 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.

FEATURESOne-piece precision offset thermosetmolded reflector.Fine Azimuth and elevation adjustments.Galvanized feed support arm and alignment struts.Galvanized and stainless hardware for maximum corrosion resistance.RF tested feed assemblyHeavy-duty Class III mount for 25 lb (11 kg) RF electronics (LNB & BUC).Skyware Global Antenna 1.8m Tx/Rx C-Band Type 183 Class III
