When you are doing the coax loss calculations, don't just assume a 
matched load. I don't know what antennas you will have at the end of the 
run, but is it possible they might have a VSWR of 1.5:1 or even 2:1 at 
the band edges? That would increase the loss over the matched loss.

At some point, open-wire feed line with matching transformers at each 
end becomes a viable option.
