Overview

The Skyware Global 1.8m Rx/Tx Class I 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.

The Az/El mount secures the antenna to any 114 mm (4.50”) O.D. mast and prevent slippage in high winds.

Hot-dip galvanizing is standard for extreme environmental conditions.
