TYPE 183: 1.8M Ku-band Rx/Tx Class III Antenna System

The Skyware Global Type 183 1.8 m Class III Rx/Tx 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 114 mm (4.50”) O.D. mast and prevent slippage in high winds. Hot-dip galvanizing is standard on this model for maximum environmental protection. A marinated version of this antenna is also available making it suitable for on-shore and offshore marine environments.

• All materials comply with EU directive No. 2011/65/EC (RoHS).

• One-piece precision offset thermoset-molded reflector.

• Heavy-duty galvanized Az/El mount.

• Fine Azimuth and elevation adjustments.

• HD Galvanized support arm and alignment struts Marinated version has all galvanised steel components finished with 2-part epoxy paint.

• Factory pre-assembled mount.

• Plated hardware for maximum corrosion resistance. Optional marinised version uses marine grade AISI 316 stainless steel hardware throughout.

• Includes Ku-band linear cross polarized RxTx feed assembly.

• Heavy-duty Class III mount for 11 kg (25 lb) RF electronics (LNB & BUC).
