1.8m Receive-Only (RXO) Antenna System Type 180 Global Skyware

This type of antenna is designed for rugged commercial applications and is built to withstand demanding conditions. Let’s break down the key features mentioned:

1. Reflector:

   • The reflector is thermoset-molded for strength and surface accuracy.
   • A network of support ribs is molded into the rear of the reflector, providing additional strength and helping to maintain its critical parabolic shape.

2. Az/El Mount:

   • The Az/El mount is constructed from heavy-gauge steel, ensuring a rigid support for the reflector.
   • It is designed to secure the antenna to any 114 mm (4.50”) O.D. mast.
   • The mount helps prevent slippage, especially in high winds.

3. Weather Protection:

   • The antenna undergoes a specially formulated powder paint process, providing excellent protection against weather-related corrosion.
   • This feature is crucial for ensuring the longevity of the antenna and its performance in various environmental conditions.

Overall, the design and construction of the Skyware Global 1.8 m Type 180 Offset Antenna suggest a durable and reliable product suitable for challenging environments. It is intended for applications where a high level of performance and resilience is required.
