Look on the cable to see if any number is stenciled on it. It might be different from the box.
From Wikipedia, the free encyclopedia
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.
Most two-way radio communication systems, such as marine, CB radio, amateur, police, fire, WLAN antennas etc., are designed to work with a 50 Ω cable.
