RG-8 Coaxial Cable, 30 m, with N-type / N-type Connectors
The 30-metre RG-8 coaxial cable with N-type/N-type connectors is designed for radio signal transmission systems where stability and moderate attenuation matter. The larger cable diameter and double shielding provide better signal quality than thinner alternatives.
The cable is suitable for antenna systems, FPV setups, repeaters and other radio equipment that requires reliable signal transmission.
Key Benefits of the RG-8 Cable
- moderate signal attenuation thanks to the solid Ø 2.74 mm centre conductor
- stable performance at frequencies up to 1.8 GHz
- effective interference shielding: aluminium foil (100%) + tinned copper wire braid (90%)
- reliable N-type/N-type connectors
- suitable for a wide range of radio systems
- durable PVC jacket
Applications
The cable is used in systems that require quality signal transmission and protection against interference.
- antenna communication systems
- FPV drones and ground stations
- radio relay systems
- repeaters and signal amplifiers
- telecommunications equipment
