A local distributor told me rg6 coax will not carry as much bandwidth as component cable will consequently my picture quality will suffer if I run 3 cables of rg6 instead of component from my a/v receiver to my hdtv. What do you experts think?

First I'm assuming you are trying to connect the component video outputs on your receiver to the component video input on your TV. Why would you use coax cable to do this? Are you making the cables yourself or special ordering them? Most of the time RG6 is much stiffer than component cables and much harder to run and work with. The bandwidth of the different cables only depends on the quality of the cables. Check out these links talking about video bandwidth:

Here is a reputable company that sells both RG6 and component cables. Both are rated to 3ghz bandwidth which is MUCH more than you will need for current HD resolutions.

Again I question why you would want to use RG6 cable instead of a normal set of component cables.

It won't matter, as long as you use good plugs, keep each identical length, and don't overdo it on length.

Thanks gentlemen for your response. I'm putting the cables in the wall is why I'm using rg6 instead of component cable. I don't like the idea of rca connections in the wall, I think I would rather have a more secure connection using coax ends then use component from the wall plate to the inputs.

Thanks ironhead and classicsat for the response. Just because my brain works this way-is bandwidth measuring the height or width of the sine wave. I may not be using the right terminology but my curiosity is: as the sine wave responds as measured in bandwidth is that a measure of how high(and low) the wave moves or a measurement of how spread out "each" wave is? Also what is then the other measurement called (whatever bandwidth doesn't measure) and is it important? Now since I don't know (obviously) what I'm talking about your response won't be offensive if you just tell me I'm an idiot! Thanks guys.

Bandwith, in general terms, is how high in frequency a cable can carry with minimal or acceptable loss.

Component video is well under what RG6 is capable of.

In most cases component cable is simply rg59 with rca connectors.

RG6 with rca connectors would be as good or BETTER!!!
