Coaxial cable varies in size and material depending on your needs. The most commonly used coaxial is RG/6, and it is available in different forms. The basic RG/6 has inner and outer conductors, accompanied by insulation, and it's intended for indoor or outdoor use. The second is just a better version of the first, with heavy waterproofing, and it's intended for outdoor and underground installation. Both are available with a messenger wire, used for grounding purposes. This type of coaxial is used in most cable television, satellite television and cable modem setups because of its low attenuation of data at high frequencies.
Instructions
1. Ask yourself if you need a coaxial cable for television, radio, telecommunication or broadcasting. This will narrow down what kind of coaxial cable to use.
2. Find out what environment the coaxial cable will be installed in. If there are high levels of electromagnetic interference, then triaxial cable should be used since it has an extra layer of shielding.
3. Draw a path where you intend to lay the cable; you may find you can receive better quality. If the run is straight, you can use a semirigid coaxial with a solid copper sheath.
4. Consult with a coaxial cable supplier if you intend to use the cable for broadcasting. Hard line is very common in radio communication, but may not be compatible with your equipment.
5. Although there are several other lower-rated RG coaxial cables, use RG/6 with a braided shield since it is the best available cable for most consumer needs.
6. Use RG/60 for high-definition or high-speed Internet to achieve the best results.
7. Find a reputable company and ask them questions that are specific to your individual needs.
