[EIDXA] Feed line question

[Jason Joens]

I have a question that's been bugging me for awhile.  What happens to feed line over the years?  Can a feed line go bad over time, increasing losses, yet still present a good VSWR at the radio? To the point where reception is noticeably weakened? Some of the feed lines on the farm have been in place for 20+ years.

I've been comparing a TH7 tribander with the triple stack on 20.  The difference is far from impressive, and I'm starting to wonder why there isn't more of a difference.  Opinions??
