Today I discovered that I have had environmental ingress beneath the outer

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
