75Ω High-Frequency Coaxial Cable Length: 10m (Measured weight: 730g) - Color: Black Thank you for viewing. This is a 75Ω high-frequency coaxial cable with both inner and outer conductors made of soft copper wire. I'm selling it because I no longer need it. Recently, aluminum is often used for the outer conductor, but if you find that inconvenient, please consider using this.
