Coaxial Cabling is designed for the transmission of high frequency signals with a minimum of loss. Coaxial wire and cable is offered with various configurations, so when purchasing coaxial cable, be sure to consider impendence, environmental temperature, working voltage, signal loss at specific frequencies, power rating and cost.

Yes. Over time, a coaxial cable will degrade and need to be replaced in order to maintain the integrity of the signal.

The most common coaxial type to carry video signals is RG-59 B/U type 75 ohm coaxial cable.

According to www.webopedia.com, Coaxial Cable is the primary type of cabling used by the cable television industry and is also widely used for computer networks such as Ethernet. Although more expensive than standard telephone wire, coaxial cable is much less susceptible to interference and can carry much more data.
