Product Name: Fiberglass Offset Feed Antenna, Ku-band Antenna
Product Model: HDS-120
Product Features
- The fiberglass offset feed antenna is molded via a 150℃ high-temperature and 2500-ton pressure process, achieving high precision and structural stability. The reflector maintains its shape without deformation under temperature variations ranging from -70℃ to 150℃.
- It boasts corrosion resistance far superior to metal materials, making it particularly suitable for coastal areas with high salt mist and regions prone to acid rain. The addition of anti-ultraviolet (UV) aging agents ensures resistance to sunlight degradation, with a service life of up to 30 years.
- As a low-density, high-specific strength, and high-specific modulus material, the fiberglass antenna offers rigidity 12 times greater than aluminum or steel of the same thickness.
- The fiberglass material is design-flexible, allowing customization with reinforced ribs, edges, flanges, and ejector mechanisms to meet specific performance requirements.
- The SMC (Sheet Molding Compound) antenna adopts automated production, enabling extremely high production efficiency—with an average molding cycle of 3–5 minutes per unit.
- The SMC Ku-band offset feed antenna integrates flame-retardant and insulating materials, eliminating toxic substance leaching during use.
- The reflector is formed in a single piece without requiring post-molding corrections. Multi-piece assemblies feature precise dimensions, ensuring interchangeability and simplified installation.
- It delivers strong wind resistance: the antenna operates normally under 8-level winds, maintains partial precision under 10-level winds, and remains undamaged under 12-level winds (with the antenna locked in an upright position). It also includes lightning protection features to safeguard environmental, personnel, and signal system safety.
