[TowerTalk] Force 12 EF-140 - Need Info from Users ( Current orPrevious )

[ersmar at comcast.net]

Dennis:

     <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.

     FWIW.
