1.2m Receive-Only Antenna System, Ku Band/C Band, Global Skyware
- Powder Paint Process
- One-piece thermoset-molded offset reflector.
- Factory pre-assembled Az/El mount for ease of installation.
- Available with a wide variety of C-band or Ku-band feeds for flexibility.
The Skyware Global 1.2 m Type 120 Offset Antenna is a robust commercial-grade product designed for demanding applications. The reflector is thermoset-molded, ensuring strength and surface accuracy. The rear of the reflector features a network of support ribs, enhancing both the antenna’s strength and maintaining its crucial parabolic shape.
Constructed from heavy-gauge steel, the Az/El mount provides a sturdy support for the reflector. This mount secures the antenna to any 73-76 mm (2.88”-3.00”) O.D. mast, preventing slippage, especially in high winds.
