Coax cable comes in many different types and grades. The two most common types are RG-58 (50 Ohm) and RG-59 (75 Ohm). Almost all CCTV applications require 75 ohm cable, thus RG-59 is the coaxial cable of choice. For cable runs longer than RG-59 can accommodate, equivalent cables with larger conductors can be used.
