Does coax have a shelf life?

I was rummaging around my father's garage the other day and came across a
roll of URM43 that I know to be over 20 years old. It looks OK and the
copper is shiny. However, can I be confident that it will not have lost any
of its electrical or physical properties? I intend to take it on holiday
with me soon and don't want it to fail.

Advice please!!

Thanks
John/G4IRN

I've never had new coax in fourty five years of hamming! I get old
stuff at flea markets or wherever and have used it with great success!
