EIA/TIA-170 Electrical Performance Standards - Monochrome
Television Studio Facilities.
EIA/TIA-170A NTSC standard used for color television.
Video standard for an Unbalanced, 75 ohm (+/- 5%), Point-to-Point, Coax (Cable) interface, at a frequency of 0Hz to 4.5MHz. By definition, the coax cable and BNC connector is Single-Ended. The analog video signal is transmitted at 1v Peak-to-Peak (0.2 to 3 volts Peak-to-Peak). This specification is still know as RS170 [RS-170] because it has been around so long. Of course EIA-170 really only talks about a Picture Line Amplifier characteristics and output format, and never mentions a coax cable. The only inference is a reference to a Single-ended output and a 75 ohm load. Color TV is called out as using 0.7v [instead of 1v], allowing Black-and-White RS170 to use 0.7 volts as well. The RS-170 standard was replaced by SMPTE 170M.

RS330: EIA standard provides details for industrial closed-circuit television (CCTV).
Editor note; I think the last time the RS-170 standard was updated in the 1970's.
So the fact that the standard calls out RG59 is understandable; however the term RG59 is no longer used.
The acronym RG is out dated and no longer used. The construction and type of cable is still valid, but goes by other names.
