Skyware Global 1.8m Class III RxTx Antenna (Type 183)

The Type 183 1.8m Class III RxTx Antenna, by Skyware Global, is a rugged commercial grade product suitable for the most demanding applications. Skyware Global 1.8m RXTX Class 1 Antenna SystemThe reflector is thermoset-molded for strength and surface accuracy. Molded into the rear of the reflector is a network of support ribs which strengthens the antenna and sustains its critical prabolic shape necessary for transmit performance.

The Az/El mount is constructed from heavy-guage 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.
