Overview

The Skyware Global Type 243 2.4 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 the reflector is a network of support ribs which not only strengthens the antenna, but also helps to maintain its critical parabolic shape necessary for transmit performance.

The Az/El mount is constructed from heavygauge steel to provide a rigid support to the reflector and feed support arm. Heavy-duty lockdown bolts secure the mount to any 168 mm (6.63”) O.D. mast and prevent slippage in high winds.

Hot-dip galvanizing is standard on this model for maximum environmental

protection. A marinised version of the antenna is also available making it suitable for on-shore and offshore marine enviroments.
