RG6,RG8,RG11,RG58 CATV Coaxial Cable
Coax cable is defined as any cable with the following properties:
A center conductor
Insulation covering the center conductor, called a "dieletric"
A braided shield surrounding the dieletric
An optional foil shield
An outer jacket
Center Conductor:
At the heart of a coaxial cable is a center conductor. Typically constructed of either pure copper (in higher-end cables) or copper-coated steel or aluminum (in less-expensive cables), the center conductor is responsible for transmitting the cable's signal. As such, it must meet certain electrical properties (such as wire resistance). The rest of the cable construction is primarily designed to help the center conductor maintain its electrical integrity.
Dielectric Insulator:
The dielectric insulator's purpose is two-fold; first, it acts as an insulator between the center conductor and the outer braided / foil shielding. Second, it helps physically hold the center conductor in the center of the cable. This is important, as signal loss can occur if the center conductor strays too close to the outer area of the cable. Various materials are commonly used for the dielectric. A few of the more common materials, in order of quality (from best to worst), are below:
1. Foamed Polyethylene (FPE)
2. Teflon
3. Polyethylene (PE)
4. Polypropylene (PP)
5. Polyvinylchloride (PVC)
