How Is RG8 Coaxial Cable Constructed?
RG8 cable uses a stranded annealed copper inner conductor made up of seven strands of 21 American Gauge Wire (AWG). The diameter of the conductor is approximately 0.0855 inches.
This coaxial cable has a solid polyethylene dielectric with an overall diameter of 0.285 inches. This material has a dielectric constant of 2.3. It has good abrasion resistance and weathering properties.
The outer conductor or shield is a wire braid made from soft annealed copper wire. Braiding cover exceeds 95% for improved shielding.
The coax cable has a protective outer jacket made from polyvinyl chloride (PVC) with an overall diameter of 0.405 inches.
RG8 Cable Applications
You can use RG8 cables for radio frequency applications up to 4,000 MHz that require a characteristic impedance of 50 ohms and for radio antennas. The cable has good power handling capabilities that range from 180 watts at 1,000 MHz up to 1,200 watts at 50 MHz. Other applications include high-quality audio recording and 10Base5 standard Ethernet connections.
