Skyware type 183 Classe III 1,8 m C-Bande Linéaire Antenne Offset

L'antenne Type 183 1,8 m Classe III C-Band RxTx est un produit robuste de qualité commerciale

Code produit: type 183 Class III 1.8m C-Band Linear Offset Antenna

The ASC Signal Corporation Type 183 1.8 m Class III RxTx 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 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" (114 mm) O.D mast and prevent slippage in high winds. Hot-dip galvanizing is standard for maximum environmental protection.
