Not sure what you mean by the "drums vertical"? Do you mean that the
wire is mostly vertical being stored on the drums; that the drums are
sitting on edge?

Hi all,
Looking for the TT brains trust to help me out with this issue:
I have two drums of LDF4-50 and one of LDF5-50 which have been stored on their
sides for around 10 years. This disobeys one of the prime directives, since
Andrew/Commscope say they MUST be stored with the drums vertical. My
understanding is that the horizontal storage may lead to inner conductor
migration.
QUESTIONS: How can I determine whether migration has occurred; if so to what
extent; and what extent should cause me to avoid using the cable for the
50m/165ft+ runs to my HF towers?
Of course, if there is gross migration, a continuity check from inner to outer
would reveal a short, but would a TDR or other method reveal performance
degradation from lesser amounts of migration?
