A better choice than RG-142 would be RG-400, which has the same
dimensions and teflon dielectric, but instead of copperweld has a
stranded center conductor (as does RG-303), making it easier to wind on
a toroid and much less likely to cause cold flow displacement of the
center conductor in the dielectric.
