    I was thinking of running S-video to my old big screen form my system downstairs system. I thought of using two coax cables for the run and wanted to know what Ohm, cable type is correct? 75Ohm? RG-6, RG-8, RG-58, /U ???

    I have plugs that can mount in a wall plate ready, so I just need the cable. The run will be 15'-20'.

    You must use 75 ohm coax for video. But both RG6 and RG59 are 75 ohms so either will work.
    I just found an old article that shows Synergy makes some SVideo adaptor cables. It has 2 wires with "F" connectors that flow into a SVideo connector in a "Y" shape. Get a pair of these and make your own.

    I used RG6 in the walls and attached a 2" piece of S-video coax at the ends. I soldered the center wire of the s-video cable to the coax, insulated it, and used metal tape to shield it. Then I twisted the shielding parts together and used a crimp connector because the solder would not stick to the shielding wire on the RG6, then more metal tape and electrical tape. Then the S-video cable was soldered to the S-video plugs I got. The plugs were mounted in wall plates and the results are excellent with out any noticeable signal loss.

    Making wires is very labor-intensive. While I encourage making your own CATV and RCA cables, the SVideo cables are much more difficult.

    They are very tiny connectors, with tiny wires and some strict shielding/spacing requirements. It's generally not recommended to "roll your own" unless you are an electrical tech.

    Where can the S-video/coax adaptor cables be purchased?

    Well, the link to Synergestic Research is one place. Here is a guy on eBay who does the same thing:
    http://cgi.ebay.com/ws/eBayISAPI.dll...tem=1333904308
    I'm not personally endorcing this seller, but I like what he has to say for several of his other auctions.
    If you buy from him, let us know how it goes.

    Avcable.com sells both the S-video break out cable and the BNC coax cables. Very good pricing with top quality broadcast cables (Gepco)
