Precision Tube Company Inc, (215) 699 5801
They make and sell a variety of semirigid coax. They will sell non magnetic
copper inner conductor, teflon dielectric.
Belden also makes semirigid coax, Part# 1673A for the .138" dia (RG-402),
1671A for the .085" (RG-405), but the center conductor is silver coated
steel. I suspect this is the stuff that Pasternak sells. It may be okay
for a solids or imaging probe where shim is not critical, but I don't think
I want to find out the answer the hard way.
I was also reminded that the Thomas Register online
http://thomasregister.com/ is a good resource.
In both cases above, minimum orders are around $300 (50 ft).
Thanks again!
