Antena 1.80 Channel Master

Descripción: Antena offset original transmisora y receptora para Banda KU

Precio: $69,800.00

Características y especificaciones:

• 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.
