Both in my experience and what I've seen from others, LMR400UF does not 
age well.

Loss increases with frequency, and I know folks who do a lot for half a 
dB. :)

400 ft of LMR600 is 1.6 dB on 10M, 2.2 dB on 6M.  The difference between 
monoband 3-el 16 ft boom Yagis and 4 element 26 ft boom Yagis for 20M is 
about 1.3 dB.

The 350 ft runs from shack to the top of my most distant tower are 
7/8-in hard line (which I scrounged used and reel ends).  My runs are 
0.9dB on 6M, 0.65dB on 10M.
