What band? if you're on HF, the loss will be pretty much not worth thinking 
about, just run decent quality coax and you'll be fine. For UHF/VHF, again, 
I'd make very sure to run as good coax as I can, LMR400 minimum for a long 
run like that, but that's the minimum I run here on those bands anyway, 
you'd probably want to go for lmr600 or hard line on UHF/VHF. For HF though, 
anything of any quality, 9913, anything like that, maybe even RG-213 should 
be fine at that length. IF you stay around 20, 40, 75 you can certainly get 
away with RG8. it's more like 10, 12, 6 if you can go there, where I'd lean 
more for 9913 or 213 minimum.
