[Milsurplus] Softening hard coax

Indirect answer.  What is special about the coax?  If it is old enough to have lost its flexibility, there is a better than even chance the plasticizer (which made the jacket flexible) migrated into the dielectric and changed the loss and dielectric constant therein.  If all you want to do is one time straighten them out, moderate heat is the answer, but changed loss/impedance may still linger.  If at all possible, replace with modern coax.  You didn't specify which GR unit it is, but I do not recall seeing anything unusual in any of the GR stuff I have used over the past 50 years.  And, replacement GR874 connectors for RG223 (and similar size) coax are still available, if that is the problem.  So are them new, expensive, I never remember the number, jobs for microwave.
