RG-6 and RG-59 are two of the most common varieties of coaxial cables, i.e., cables that conduct electricity to transmit signals of radio frequencies, computer networks, and cable televisions. You may also find these cables designated as RG-6/U or RG-59/U, but there is no difference. Both types differ in their construction, uses, and range of capabilities. We shall now look at how one can tell the difference between RG-6 and RG-59 coax cables, and identify one from the other.
How to Identify RG-6 and RG-59 Cables
Construction: Ideally, to identify if the cable is RG-59 or RG-6, one only has to look at the jacket/outer covering, where the details of the cable are printed. However, if this printing is not visible, look for the thickness and the flexibility of the cable. Both cables have 75 Ohm resistance. However, the RG-59 cable has a 22 American wire gauge center of multiple strands of wire, while the RG-6 cable has 18 American wire gauge center with a solid copper core. This means that the RG-59 cable is smaller in diameter than the RG-6. Further, RG-6 cables can have additional foil and wire braid shields along with thicker
