In the latest (I think) version of his excellent Managing Interstation 
Interference," W2VJN notes that he observed degradation in the measured 
performance of stubs made of LMR400 that had been sitting in his garage 
for a bit less than a decade. He seemed to think it was due todegraded 
contact between the foil and braid shields. This was written several 
years ago. He may have more to say about it by now.
