[Towertalk] coax losses over time

[Tom Frenaye]

I've seen lots of printed references to the fact that coax losses increase over time but have never seen any "hard" data.   Are there any real studies of coax deterioration?     Makes sense that it would deteriorate more quickly outside, in the sun, or buried, than inside, for example.

I assume that the primary cause of deterioration is the dielectric material, correct?   How does CATV hardline compare to something like RG-8 foam, for example?

Or, is it all so variable that it makes more sense just to measure the loss on each one.  (i.e., no rules of thumb apply)
