Descripción: Antena offset original transmisora y receptora para la Banda KU.
Características y especificaciones:
The Channel Master Type 243 2.4m Offset Rx-Tx Antenna is a rugged commercial grade product suitable for the most demanding applications. The two-piece reflector is thermoset-molded for strength and surface accuracy. Molded into the rear of each reflector half 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 6.63 i n .O. D.mast to prevent slippage in high winds. Hot-dip galvanizing is standard for maximum environmental protection.
