The Belden 9913 RG8/U coaxial cable (black) is low loss with an "air" dielectric. This 50 Ohm coax cable has a solid center conductor and a semi-solid polyethylene dielectric. A 100 percent shield coverage prevents loss.

The braided coaxial cable offers similar performance compared to corrugated copper cables but provides higher flexibility and simplified connectorization. This RG8 cable requires 9913 specific connectors.

The Belden RG8/U low loss coaxial cable with "air" dielectric is available in bulk and is priced per foot.
