7.3m Fixed Earth Station Antenna
model:
- Commodity name: 7.3m Fixed Earth Station Antenna
- Product Description
-
Overview
The JP-A4.5M-C/Ku is a 7.3 -meter ring-focus satellite communication antenna with an A-E pedestal, supporting dual-band (C/Ku) transmission and reception. It complies with GB/T19001-2008, GJB9001B-2009, and ITU-T/ITU-R technical standards.
Technical Features
- High-Efficiency Dual-Reflector Design
Features a shaped dual-reflector system for superior electrical performance, including high gain, low sidelobes, and excellent cross-polarization isolation.
- Robust structural Engineering
Optimized for aesthetics, rigidity, and ease of installation, with exceptional wind resistance.
- Advanced Anti-Corrosion Protection
Reflector panels coated with triple-proof strontium yellow primer and polyurethane topcoat.
Steel components undergo sandblasting, zinc spraying, and dual-layer coating (strontium yellow primer + polyurethane) for maximum durability.
