[TowerTalk] Looking for a good small coax for 160, 75 and 40

[Bob Nielsen]

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.
