I once used RG-400 to feed an elevated 80 meter dipole. It has a
teflon dielectric (similar to RG-142 except that the center conductor
is stranded copper instead of copperweld) so power handling wasn't a
problem. I don't know if it is more flexible than LMR-240 or not.
It's not inexpensive, but held up nicely for 15 years until the
station was dismantled. I am currently running 600 watts into RG-8X
but wouldn't want to go much higher in power than that.
