RG (Radio Guide) is a military term.

RG-59

Used for low-power video and RF signal connections. The cable has a characteristic impedance of 75Ω (ohm)s, and a capacitance of around 20pF/ft (60pF/m).

Commonly known as old cable TV coaxial cable or CCTV cable.

Not suitable for most two-way radio application.

RG-6/U

A larger family of cable design not specific to one in particular. RG-6 and RG-6/U are the same. The cable family has a characteristic impedance of 75Ω. It has a smaller conductor and the dielectric insulation is thicker than RG-59. It was made to work better with broadband data and satellite application. Handles frequencies higher than 50Mhz better than RG-59.

Commonly known as small dish satellite TV cable.

Not suitable for most two-way radio application.

RG-58

Used for low power signal and RF connections. The cable has a characteristic impedance of either 50Ω or 52Ω. RG-58 CB coaxial is an affordable choice for basic CB installations. RG-58 (CB cable) has a high loss factor in VHF and UHF frequencies, so it really only is useful in runs less than 50 feet for frequencies above 100 MHz, and 20 feet for frequencies above 400 MHz.

Commonly used for Citizens Band radio.

RG-8/U

This cable is suitable for 50-75 foot runs in the VHF/UHF range. The cable is considered by some to be obsolete. The cable has a characteristic impedance of 50Ω.

RG8x is 50 Ohm cable that is about the same physical size as RG6. It is fairly high loss however and is not that well suited for 70cm except in short runs, however, is suitable for longer runs in the VHF 2m band. RG8 (RG213) is larger 50 Ohm cable that has less loss than RG8X.

RG-213

Considered to be a replacement to RG-8 and much better suited for both VHF and UHF operation. The cable has a characteristic impedance of 50Ω. The specifications for RG-213 are tight as compared to RG-8, increasing the consistency from one manufacturer to the next. RG213 is low loss cable with a non-contaminating jacket.
