About RG58
RG-58 is a classic flexible 50-ohm coaxial cable with a 0.195" outer diameter, offering an excellent balance of flexibility and performance at a low cost. Its braided shield provides good EMI rejection and its thin profile makes it easy to route through tight spaces. Common applications include amateur radio, CB radio, networking equipment connections, and general-purpose RF jumpers up to 25 feet.
