LMR240 in all of its different flavors is top notch. You want to limit its
use to around 500 watts. More than that and I recommend moving up to LMR400
in its many flavors. For general jumpers in your shack, your best bet is
LMR400UF.

My station has all LMR240. Easy to work with, and not too heavy.--Matt,
