The SDY-50-12 feeder cable is a high-performance coaxial cable designed for demanding communication systems. Featuring helical corrugated copper conductors and a PE dielectric, it ensures low VSWR and minimal signal loss across frequencies up to 4.60 GHz. Ideal for broadcast transmitters, mobile networks, radar, and satellite stations, it supports peak power up to 38 kW and operates in extreme temperatures (-55°C to +85°C). Its compact design (19mm jacket) and flexible bending radii enhance installation versatility, while robust construction guarantees durability in diverse environments.
High peak power handling up to 38 kW with broad applications across medium wave, FM, and TV transmitters.
Wide frequency range from 550 kHz to 4.60 GHz, suitable for communication, radar, and satellite systems.
Durable helical corrugated copper tube conductors ensuring low attenuation and stable impedance (50Ω±0.5n).
Flexible design with minimal bending radii (70mm single, 200mm multiple) for easy installation.
Robust temperature resilience (-55°C to +85°C operational range) for harsh environments.
Low DC resistance (0.40 Ω/km inner, 0.12 Ω/km outer) and PE jacket for reliable signal transmission.
