Coaxial Cable, RG59UW

Many industries and individuals use coaxial cable RG59U in the transmission of communications signals. Most notably audio, video, or network signals. You'll recognize this style of cable if you've looked at the back of your cable box or modem. Many people don't even realize that the name of these cables is actually coaxial. Many people call them coax. So, what does coax, or coaxial mean?

The term coaxial indicates the cable possesses two concentric conductors. These conductors are separated by an insulating material. Put simply, the inner conductor is encased in a cylindrical material that insulates it. This insulating material is surrounded by a tubular conducting shield. There may even be another insulating layer after the shield in certain cases. Most frequently, the inner conductor carries the signal carrying voltage while the shield is kept at ground potential. Why create a wire like this? Well, this type of design offers several benefits. Most important is that this design restricts magnetic and electric fields. The fields are restricted to the internal insulating material. This helps to reduce leakage outside the shield.

Why use Coaxial Cable RG59U? This type of coaxial cable has a wide range of uses. Most commonly, it is used for low-power video or RF signal connections. One notable characteristic of coaxial cable RG59 is its impedance of 75 ohms. It is also slightly smaller than RG6 making it ideal where limited space is an issue. Selecting the correct coaxial cable is not always an easy choice. Contact a Pacer expert today with questions that you have.
