Type 180
1.8m RECEIVE-ONLY
OFFSET ANTENNA SYSTEM
FEATURES
One-piece precision offset
compression molded reflector.
Sturdy AZ/EL mount with elevation scale.
Single bolt fine elevation adjustment.
Galvanized .75” O.D. feed support legs.
Factory pre-assembled mount.
Cadmium-plated hardware
for maximum corrosion
resistance.
Available with a wide
variety of C-Band or
Ku-Band feeds.
The Channel Master ® Type 180 1.8m Offset 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 the reflector is a network of support ribs which not only strengthens the antenna, but
also helps to sustain its critical parabolic shape.
The AZ/EL mount is constructed from heavy-gauge steel to provide a rigid support to the reflector. Four
heavy-duty lockdown bolts secure the mount to any 4.50” O.D. mast and prevent slippage in high winds.
A specially-formulated powder paint process offers excellent protection from weather-related corrosion.
Hot-dip galvanizing is optional for extreme environmental conditions.
