Type 180 C-Band Receive Only Antenna
The Skyware Global 1.8M Type 180 Offset 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 its critical parabolic shape. This ensures outstanding RF performance for transmit and receive applications such as iDirect internet service and remote satellite broadband applications.

Rugged Reflector Mount
The Type 180 C-Band Az/EI mount is constructed from heavy-gauge steel to provide a rigid support to the reflector. The Az/EI mount secures the antenna to either a 60 mm 12.38"] or 73-76 mm 12.88"-3.00") 0.D. mast and prevents slippage in high winds.

Corrosion Proof Antenna Backstructure
A specially formulated powder paint process offers excellent protection from weather-related corrosion.
