(Sorry, this is now triple-posting, anyone upset with it please tell

me)


Hi all.


About a year ago I made a VGA to RGBHV BNC cable, out of

Ixos cable and Ixos BNC's. The BNC's are these VERY fancy

gold-ones


When I made the cable, I couldn't help wondering if the Ixos

idea of using three(or so), little wires instead of one single

conductor is flawed. I mean, normally the very stiff single

conductor just fits right in, but the multiple very soft ones

from the Ixos sort of....well, it didn't feel right.


I've just been to the electronics store, and I bought some

75ohm cable(cheap, costs about 1$us per meter) and some

75ohm BNC plugs.


What do you think? Should I make a new cable, or the Ixos way

good enough? Multiple soft wires vs. stiff single conductor...gold

covered BNC's vs. normal?


Thanks for your time,


Nicholas


EDIT: The RG59 I bought seem to have a cobber-layer on the conductor,

with some other metal inside. Is this bad?

So-so. Not optimal, but RG59 should be more than enough for almost any AV use unless the run is extremely long. It happens that RF signals (and video to some degree) tend to travel on the skin of a conductor rather than inside it. As a result, conductivity of the outer layer matters the most. (The lower the frequency, the deeper the skin layer.)

The coax you got, sounds like copper coated steel. This product typically is used in places where strength is important. Like cable TV systems. It's not optimal for highest quality video, even though there is truth to high speed video tending to travel over the surface of the wire, vs. the core. Optimally, you want oxygen free copper conductor in FEP teflon or foam pe or silver coated copper in FEP teflon.

Nich, regarding single solid conductor versus stranded, as in the premium Canare L5CFB solid and LV77S stranded, for home use, you normally could not tell the difference in performance for video. For extremely long runs, as in a satellite antenna to indoor boxes, the solid conductor's better specs might show up as a performance difference.

i'm using a component video cable, monster 2 as my coaxial. do you think a bog stand digital coax from acoustic research would be worth it? do you think it matters if it a componant cable?

Im only after something very cheap if I need to upgrade.

Stranded center conductors are used only for the purpose of making the cable more flexible. Solid copper center conductors perform better than stranded, but are not as flexible, and the difference in performance is minimal.


I think you can buy different BNC plugs for stranded vs solid center.

Using the right ones makes it much easier to get a good connection.


Gold plating is useful only for corrosion resistance.

Where I live, I only have one store that carries RG59 cable, and it's

copper-plated metal. :(
