Description
RG59 CATV/CCTV video coaxial cable is a coaxial line commonly used in video distribution systems, including cable television (CATV) and closed-circuit television (CCTV) applications. This television coaxial cable can provide good conductivity and signal transmission while remaining cost-effective. The coaxial line is also shielded to reduce electromagnetic interference (EMI) and radio frequency interference (RFI) which can degrade signal quality.
