[Towertalk] coax losses over time

[frenaye@direcway.com (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)
