    I just ordered some Parts Express gold S-Video connectors (091-1216)but I have a question about which wire to use. Belden has 2 wires which look promising:

    1808A (which is 2 shielded (90% coverage), 30 ga tinned copper connectors within 1 outer jacket)
    7700A (which is 2 shielded (98% coverage copper braid), 30 ga tinned copper connectors side by side, plenum/teflon insulation)

    Now I know about the magical properties of teflon. The 7700A also has better shielding, but the side by side geometry may pose a slight problem with the S-Video connector.

    Any thoughts?

    Thanks,
    Bob

    Not to belittle your idea, buy why are you making DIY s-video cables? I can understand speaker cables, and RCA, BNC, component, and composite. S-video isn't exactly a crimp on operation.

    I've heard that s-video cables can be touchy to make. Myself, I just bought some Dayton Audio s-video cables from Parts Express. I plan on making my own RCA cables for audio, but I decided to just buy some premade s-video cable because it didn't seem worth the hassle.

    I've turned into a self-confessed soldier junkie. I can get a 5' sample length of either of these wires for free. So the cost is only about $5 for the connectors and my time/patience to soldier the tiny, tiny wires - vs about $35 for store bought of the same/less quality.

    Thanks for your concern.

    For short runs, the 1808A works fine. For longer runs, I suggest buying/building a break-out cable.

    Build a short (6") cable from 1808A with an SVHS connector on one end. On the other end, split the coax cables and attach male BNC connectors. Then make your run with 2 cables of high grade video cable with BNC's on the ends.

    I've read the 7700a is better. Furthermore, shielding is very important in video cables. You can add a telescoping shield for even better results.
    BTW, I own some generic SVHS cables that have the same zip configuration as the 7700a.
