The SDY-50-22 Feeder Cable is a premium coaxial solution engineered for high-power signal transmission in demanding communication networks. Featuring helix-corrugated copper conductors and a PE-insulated dielectric, it minimizes signal loss across medium wave, FM, and TV broadcasting systems. With a peak power handling of 73kW and a cutoff frequency of 6GHz, it excels in high-frequency applications like radar and satellite ground stations. Its lightweight design (860 kg/km) and flexible bending radii simplify installation, while a robust temperature tolerance (-55°C to +85°C) ensures uninterrupted performance in extreme climates. Ideal for low-VSWR, high-reliability connectivity.
Peak Power Versatility: Supports up to 6kW (medium wave), 3kW (FM), and 300W (TV decimeter wave) for diverse broadcasting applications.
Durable Construction: Double helix corrugated copper tubes (inner/outer) enhance mechanical strength and signal integrity.
Broad Compatibility: Low attenuation and VSWR enable use in radar, satellite stations, and microwave relay systems.
Flexible Installation: Compact design with 90mm (single) and 300mm (multiple) bending radii for adaptable deployment.
Extreme Resilience: Operational temperature range from -55°C to +85°C ensures reliability in harsh environments.
High-Frequency Performance: Stable 50Ω impedance and 3GHz max frequency for consistent signal transmission.
