Overview

The Skyware Global 75cm Rx/Tx Ku-Band Elliptical LFL 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/Skew mount, constructed from heavy-gauge galvanized steel, provides a rigid support to the reflector.

The mount secures the antenna to any 60mm (2.38”) O.D. mast and prevents slippage in high winds.

The Az/El/Skew mount allows for precise alignment of the elliptical reflector to the geostationary arc, taking full advantage of the antenna’s performance.
