I would go with LMR 400 ultra flex and be done with it.
Both in my experience and what I've seen from others, LMR400UF does not
age well.
About .8 db loss for 100 ft.
Loss increases with frequency, and I know folks who do a lot for half a
dB. :)
I have runs in excess 400 ft, so I use LMR 600 for the runs to my towers.
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.
