To extend a coax cable without special tools you will need a second coax cable. You can plug the second coax cable into the end of the first one (the end that is plugged into the wall).
coax television through a cable company in a home should not have any power on it if it dose it might be coming from a TV or a VCR or some sort of coax tuner on a unit satellite on the other had dose run voltage on there line to work the dish properly
Cable modems use RG-6 coax cables.
There isn't or shouldn't be any power in coaxial cable. It is just for the TV or computer hook up. Just so you can receive the signal from the broadcaster or Internet. In several ways the previous answer is wrong. Firstly coaxial cable is exactly like normal 2 wire cable (fig8 cable) except that instead of two separate wires running side by side separated by insulation) one wire is inside the other (again separated by insulation). There are many different types of coax (probably hundreds eg one i use is rg-58 which is for two way radios, another is rg-6 which is used for tv coax) secondly- if any signal is to be passed through a cable- there has to be power flowing through it- it may be incredibly small (microvolts like from your tv antenna) or very large (hundreds of volts like in a high powered radio transmitter) Even in a tv coax, if you have a `masthead amplifier' that only has 1 cable running up to the antenna and a funny box behind the tv that has 2 coax leads running into it and a plug-pack from a PowerPoint going into it as well- you would find that you are actually passing power up the coax from the PowerPoint plug-pack to the electronics up on top of the tv mast - power going up and tv signal coming down the same coax at the same time- saves on another two wires having to be run!!! Many `cable' tv or internet cables have a similar `power over coax' arrangement for powering amplifiers on long cable runs, this is normally stopped by a filter before the end users outlet however (if the filter is faulty this can be the `tingle or zap' that you sometimes get when touching the outer screw connector of the coax plug)

This would depend upon your TV and the receiver and if it has a coax port available on the back. You can use an RG6 coax cable between the receiver and TV. Most newer HD receivers do not have a coax port on the back
The best size is RG 6 coax. However for short runs RG 59 will work.
For Dish Network, we use RG6 coax cable to allow a higher frequency range for the satellite signal from the dish to your receiver. Any coax cable not rated at RG6 could affect the signal.
It's the coax cable used for Thick Ethernet.
Typical coax cable uses a different standard than RCA. You will need to use a converter box.

UTP & COAX cable's are used
