Cable Wire

Can i splice a coaxial cable wire for my TV without losing signal quality?

The cable that the installers put in is too short for where I want to put my TV. Can I get a splicer like for a phone, or do I need to replace the wire at the source?

Theoretically, any additional splice adds attenuation to the signal, so you would lose signal quality. However, the quality lost is, in most cases, negligible. In other words, you would probably not notice it at all. However, for best results, you can go buy a longer coaxial cord. They are not super expensive. Or, you could call the cable company, maybe they would give you a longer cable if you ask. However, there is no "need" to speak of as far as replacing the wire.

Does the size of a cable wire affect the picture quality?

I just bought a new cable wire for my television because I needed a longer one, however, I haven't hooked it up yet. It is a slightly thinner cable. I've heard that a thicker cable delivers a better picture. Is this true?
The length of the extension cable is 50 feet; it bridges from a splitter on a cable jack to my Comcast digital cable box.

For a run of a few hundred feet, yes the cable thickness will make a difference. For a run of under 10 feet, like in most homes, you are not going to see a difference. For a short run, I would probably have difficulty seeing a difference with actual test equipment!

I hope this helps. Please return and select a Best Answer from all of those submitted.
