The cable of choice for TV service now and the last 8 to 10 years with digital signals is RG-6U. The RG-59U was the cable of choice for the cable companies before that and is still sold by some stores. I used a 1000 foot spool of RG-6U when I did the new house. I had called the cable company (Charter Cable) and asked which one to use. They told me that they had phased out the use of RG-59U and were replacing it when upgrading service to new subscribers. Too much signal loss with the new digital signals for cable service.

> RG-58/U is a type of coaxial cable often used for low-power signal and RF connections. The cable has a characteristic impedance of either 50 or 52 Ω. "RG" was originally a unit indicator for bulk RF cable in the U.S. military's Joint Electronics Type Designation System. There are several versions covering the differences in core material (solid or braided wire) and shield (70% to 95% coverage).
> The outside diameter of RG-58 is around 0.2 inches (5 mm). RG-58 weighs around 0.025 lbs/ft (37 g/m), exhibits approximately 25 pF/ft (82 pF/m) capacitance and can tolerate a maximum of 300 V potential (1800 W).[1] Plain RG-58 cable has a solid center conductor. The RG-58A/U features a flexible 7 or 19 strand center conductor.
