Type 183 1.8M RECEIVE/TRANSMIT OFFSET ANTENNA SYSTEM FEATURES One-piece precision offset compression molded reflector. Heavy-duty galvanized AZ/EL mount. Fine azimuth and elevation adjustments. Galvanized feed support arm and alignment struts. Galvanized and stainless hardware for maximum corrosion resistance. Available with a wide variety of C-Band and Ku-Band Rx/Tx feed assemblies and ODU mounting kits. The Channel Master ® Type 183 1.8m Offset Rx/Tx Antenna is a rugged commercial grade product suitable for the most demanding applications. The reflector is compression-molded for strength and surface accuracy. Molded into the rear of each 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 and feed support arm. Heavy-duty lockdown bolts secure the mount to any 4.50” O.D. mast and prevent slippage in high winds. Hot-dip galvanizing is standard for maximum environmental protection.
