1.8m Rx/Tx Class I Antenna System

Skyware Global 1.8m Rx/Tx Class I Antenna, a robust commercial-grade solution designed to meet the highest performance standards. Here are the key features:

Key Features:

1. Rugged Construction:
   • Built for demanding applications, this antenna is crafted with durability in mind.
2. Thermoset-Molded Reflector:
   • The reflector is thermoset-molded, ensuring both strength and precise surface accuracy.
   • Integrated into the rear of the reflector is a network of support ribs, enhancing structural integrity and maintaining the crucial parabolic shape required for optimal transmit performance.
3. Heavy-Gauge Steel Az/El Mount:
   • The Az/El mount is constructed from heavy-gauge steel, providing a sturdy support for the reflector.
4. Secure Mast Attachment:
   • The Az/El mount securely attaches the antenna to any 114 mm (4.50”) O.D. mast, preventing slippage even in high winds.
5. Hot-Dip Galvanizing:
   • Standard hot-dip galvanizing is implemented to withstand extreme environmental conditions, ensuring longevity and resilience.
