Cable length question

845 Views 8 Replies 4 Participants Last post by  Targus,

I was posting over in the design & construction forum, but it was mentioned that I might be able to find a better answer over here.


My setup consists of a projector, receiver, dvd player, htpc, and some consoles. I need to buy some cables to connect the video up from the receiver to the projector, which would run about 32.75 feet. In my search for cables, I've found some cables that come in 35' (roughly what I need, with a little bit of slack), but others only came in 25' or 50' sections. Would 50' s-video and composite cables suffer serious signal degredation, or would it still provide a decent image? I'm not quite as concerned with the image quality from these two sources, as they will only be used for my gamecube and possibly vcr, but again I wouldn't like them to be unwatchable.

What is the price on those 50 ft cables?

If the quality is there then it will be fine, The more copper the better.


If you wanted to make your own w/ rg6 you could.


A commonly recomended wire is the belden 1694a

found here for .42 a foot.

You would need to put your own ends on

If you do not have a crimper or a compression tool, then I would recomend you have them put the ends on.


Hope this helped.

The resolution on both of them is not very high to begin with.


If you went with a regular S-video cable, there probably would be some degredation at that length since the conductors are so small. However, if you used two RG-6's (or RG-59's) and then used an s-video adapter for it, you shouldn't have any problems.


The composite video should be fine if you went with RG-6 (or RG-59).


In both cases, be sure to use a coaxial cable with a solid copper center conductor. The Belden 1694a mentioned above is a great cable but might actually be overkill for this application.

or he can run one rg6 and terminate with an RCA and get a S-video to component adapter instead of running double cable. Save $20 ish.

An s-video to component adaptor is called a transcoder...and the result would look like crap.

Such a big word for a little adapter.


Maybe I was thinking of something else.


Its about the size of my thumb and did not give me a bad picture.

Maybe you're thinking of a composite adaptor? I know those are small and not expensive.


For the 50' s-video cable, I'm looking at:

And for the 50' composite cable, I'm looking at using this coax audio cable once it comes back in stock:

That component cable seems to be a good one as it has a copper center and copper braid. Pretty good deal.


As far as the S-video one, they don't give too much info on that. Pretty cheap as well, might be worth just buying it and trying it out.

Composite and component are big words as well...you should figure out the difference between them.
