Type 184 Ku-Band Dual Optics Antenna System
The Skyware Global Type 184 1.8M Dual Optics Tx/Rx Antenna is a rugged commercial grade product suitable for the most demanding applications.
The dual optics design provides the superior cross-pol discrimination for optimum performance on the Eutelsat satellite system.
The reflector is thermoset-molded for strength and surface accuracy. Molded into the rear of the reflector is a network of support ribs which strengthens and helps to maintain the parabolic shape necessary for transmit performance.
The heavy-gauge steel Az/El provides a rigid support to the reflector and feed support arm. Heavy-duty lock-down bolts secure the mount to any 114 mm (4.50”) O.D. mast and prevent slippage in high wind.
Hot-dip galvanizing is standard on this model for maximum environmental protection.
