Practical to make your own custom cable
Alex Eisenhut:
Suppose I want a one meter length of cable about 5mm in outer diameter (.2 inches) that contains two thin 50 ohm coaxes and 5 or 6 24AWG wires... Think its possible to shove all that into a piece of 8mm (unshrunk) silicone heat shrink tubing and have it end up being a usefully flexible cable?

I have no idea what this stuff acts like once shrunk or "recovered" in the heat-shrink tubing vernacular.
Anyone ever try this?
It would be for a Tektronix P6042 current probe, often the probe cable fails.

Think I'd recommend loom (e.g. the braid stuff) over tubing (spaghetti or shrink)?

I've done that before for my experimental Commodore SX-64 keyboard cable. It works, but it was not as flexible as I want this P6042 cable to be.

A VGA cable has 3 coaxes and 5 signal lines plus assorted ground returns. Would that work?

Those are 75 ohms and too thick... good idea though.
