Hi Tom,

You said,

>The most simple system is just to build a "fat" dipole. If you fan the ends of 
a dipole out several feet with a spreader, it is quite easy to cover the CW and 
SSB areas without any type of mess. A cage dipole would also work.<

A natural question is whether this approach will broadband my 80M wire Yagi if 
I fan the ends of all three elements. Not just swr bandwidth, but gain and f/r 

As an aside, when you fan the ends of a properly tuned single-wire element, as 
you describe, what happens to its resonant frequency? Does it end up needing to 
be shorter or longer?
