colored 50 Ohm coax
« on: May 15, 2024, 08:31:48 PM »
Hi all,

I have a rather simple question.
Does anyone know about a manufacturer of colored 50Ohm coax cable?
I search for some 50Ohm coax (RG174 and RG58) in different colors.

The only cables I can find are either audio cable which isn't really 50Ohm or video cable, which is 75Ohm.
As a reference, something like this:
https://www.vandammecable.de/produkt/van-damme-plasma-grade-standard-miniature-75-ohm-video-coax-rg179-koaxialkabel/
But 50Ohm.


Does anyone know where I could find such cables, maybe a seller, a manufactuerer or some kind of lead?



Thanks and greetings,
Michael

Can you use stuff even thinner than RG174?   At work we use tons (well, kilometers) of 50 ohm cable with blue insulation, and in the lab I might have some yellow cable we used to use.  Without RG numbers, these are custom part numbers used in cable bundles for test equipment.  How much do you need?  Would scrap pieces shorter than 1 meter be useful?

Thanks, klugesmith,

I am building some different attachment for scope probes / scope probes themself. I would like to make the whole cable the same color as the scope channel so normally yellow, blue, red and green.

Nontheless, I am always interested in some unusual coax so I guess I am listening. :)
What kind of dimensions do your cables have? I'm not really limited to specific dimensions, however the microcoax as used for example on UFL connectors might be a little too thin.
60 to 100cm pieces would be about right for what I need but some shorter pieces might be useful as well for general labwork.


Greetings,
Michael
