RG8 Coax Cable

What Are RG8 Coax Cables?

RG8 coaxial cable is a relatively large diameter, 50-ohm coaxial cable. Its primary applications include broadcasting, amateur radios, and antenna feed cable. It is suitable for radio frequencies up to 4,000 MHz. Signal attenuation at 4,000 MHz is 23 decibels per 100 feet. Attenuation drops sharply at lower frequencies and is 7.4 dB/100ft at 1,000 MHz. RG8 coax has a braided copper shield with a minimum 95% covering that provides good radio frequency shielding. The cable's maximum voltage rating is 4,000 volts.
