RG59 Coaxial Cable
RG59 Coaxial Cable aka Coax Cable is cable generally used for audio and video signal. RG59 Coaxial Cable is highly shielded due to the weak nature of radio signals. RG6, RG59, Coaxial Cable makes an ideal medium to send signals over. RG6, RG59, Coaxial Cable consists of an inner core cable made of copper which is the cable that the signal is sent on, this core cable is coated with a plastic insulator which is then covered in aluminum foil as well as a metallic woven shield generally consisting of aluminum or copper. The outside of the insulation and shielding is a plastic coating.
There are two major types of coaxial cable: RG-6 and RG-59. RG-59 coaxial cable's sole use is for CCTV (closed circuit television) applications. RG-59 coax is often used for low powered video and base-band video frequencies such as composite video mostly found in security camera use. RG-6 coaxial cable is used to route cable television signals to and within homes replacing RG-59 as the standard for CATV (cable television). RG-6 is also used for most professional video applications. Both RG-59 and RG-6 coaxial cable come in PVC and Plenum coating.
Coaxial cables, though not as popularly used as it once was, can be used to create Ethernet networks. More commonly, its used for television and radio signals. Coaxial cable is layered several times to help protect the cable from cross-talk or leakage of signal. The single center cable is either a single copper wire, a stranded copper wire, or a copper coated wire. This layer is then covered by a plastic insulating layer, then a woven metal shield and finally by a plastic sheathing.
There are three common types of coax cable: RG6, RG59, and RG59 Siamese. RG6 coaxial cable is much thicker than RG59 coaxial cable which gives it a stronger signal. Its commonly used for satellite usage because of its higher GHz intensity and extra shielding than the RG59 has. RG59 Siamese coaxial cable has the ability to run a signal as well as power, it has single coaxial wire but it also has an eighteen gauge pair that can carry AC or DC power to a video camera. Both the coaxial and the stranded pair exist in different but connected shielding.
