<Better> I can't say, as I never used an EF-140. But I have had a CC
D-40 rotatable up on my tower since 2001. It's SWR curve met specs (200
kHz) and the low spot on the SWR curve is just where I set it based on CC's
graphs in the manual.
It's not very directional, but I'm supposing that's because of its
compact size - doesn't produce the typical bowtie pattern of a full-sized
dipole with deep nulls off the ends.
