Component Video cable long runs

HDTV Forum · Post by **HDTV Forum** » Sun May 23, 2004 6:33 pm

My Mitsubishi 65" rear projector is at one end of my entertainment room, the stereo rack is built into a wall 50 feet away in the back of the room. If I run custom made component video cables from the rack to the TV will it cause any signal loss or other problem?

Most likely, yes. But having a very good custom made cable should help to reduce the amount of loss greatly.

Cables NEVER improve signal quality only decrease it......just get the cables that give least amount of signal loss.......

Use 75 ohm video cable that meets or exceeds Belden 8281 (RG6 is the wrong cable) plus you MUST use 75 ohm connectors. Unless you are skilled at properly terminating the cable you would be best served having this custom run made for you by a specialty dealer or servicer such as Mastertech.

I agree with Richard on this . Belden 8281 is the best broadcast quality video cable , the industry standard . 8281 is designed for tv studios where where cable lengths over 100 feet are common . It is designed for baseband video and has a solid copper center conductor . RG6 has a copper clad steel center conductor and is designed for higher radio frequencies which travel proportionally on the surface of the center conductor . Belden 8281 is available in a variety of colors and costs about $600 for a 1000 foot roll . black is available in 500 foot rolls . Mouser electronics (www.mouser.com) will sell 100 foot lengths and the last time I ordered in 1997 they also sold it by the foot . You will have to use bnc connectors on the cable .

This vendor was recommended on Audiogon and I had a set of custom 30 ft component cables made. They'll make any length and while they don't say if their cable is Belden they do give the specs on it for comparison.

Since nearly all A/V receivers use RCA connectors for video it is also important you keep your video cables at about 6 feet or less. RCA connectors are not really meant for such high frequency applications and will cause ringing which looks like edge enhancement.

For long runs it is best to use BNC connections where ever possible and yes that is more expensive due to BNC RGB or component switching. BNC connectors are designed for high frequency applications and will not introduce the ringing notorious with RCA connections.

I have been revieing a lot of cables recently. The fact is that I am not seeing a lot of differnence. I just reviewed AVIC (new company) and they compared equally with more expensive companies at the same distance.

I have received many guestions on whether high end cables are better than low end. After my testing, I am saying medium end cable will produce more than acceptable results. I would spend my excess dollars elsewhere concerning video performance.
