[Test-Equipment] Repair HP410B (triax cable request)

[Barry]

I have an HP410B I'm going to refurbish.  As part of that process, I may need to replace the triax cable that feeds the AC probe.

I think Belden 9222 is a possibility; however, I don't find that online in anything less than 100 ft. spools and at more than $1 per foot, that ends up a bit cost-prohibitive.  Anyone happen to have any of that for sale (by the foot)?  I think the original cable is about 4 feet long.

Any other recommendations on this?

Thanks,
