Plenum RG58 is designed to meet the strictest of electrical codes; our plenum cable meets or exceeds many common cable standards. The Belden 82240 RG58 is commonly used for low-power signals, RF connections, Ham radio, Thinnet 10Base2, and more. This cable features a UL listed CMP rated Flamarrest jacket. Internally this cable is protected from RFI and EMI interference by a 95% copper braid shield. The center conductor is made from 20 AWG solid copper. This bulk cable is sold by the foot—order just what you need. RG58 is commonly terminated with a BNC, N, TNC, or UHF connector.

No reviews for this product

Q: What does AWG stand for?

A: AWG is the gauge size and denotes the thickness of the cable. The lower the gauge of the cable, the thicker the cable will be. AWG stands for "American Wire Gauge" and is a standardized wire gauge system used throughout the industry.

Q: What does the jacket rating CL2, CM and CMP mean?

  • CL2 is the standard type of PVC jacket used for low voltage cable. CL2 rated cables are often referred to as in-wall rated cables and can be run almost anywhere except plenums. CL2 is more common for non-professional use.
  • CM is standard communications cabling that is not run in walls or in plenum air spaces.
  • CMP is a rating that is given to cables that have passed a stringent burn test and are able to be run through plenum air spaces. Plenum air spaces include drop ceilings and non-ducted HVAC air returns.

Q: What is the difference between 50 and 75 Ohm Cables?

A: 50 and 75 Ohm values refer to the impedance of the coaxial cable. Impedance is a measure of resistance, in the cable, to the flow of electrical energy. There really is no “good” or “bad” impedance, just the right impedance for your application. For 75 Ohm cable, the primary application is the transmission of a video signal. In the case of 50 Ohm cable, it is a data signal that is for the most part being transmitted.

Q: What does “RG” mean?

A: The "RG" is short for "Radio Guide," a term that dates back to the World War II era, when the military made heavy use of coaxial cable, and developed a set of standards to specify different grades of coax and their applications. Even though we still refer to coaxial cables by their original RG numbers today, these standards are now obsolete in regard to actual military use.

Q: What is the difference between solid and stranded conductor cable?

A: Solid conductor cable is made from a solid piece of wire. Because of the solid core of these cables they will be more rigid than stranded cable, but can carry a stronger signal than stranded wire.

Stranded conductor cable is made from multiple tiny stands of smaller gauge wire. Because this cable is made with smaller strands of cable it is more flexible than solid core wire.
