If you do this, be sure to download the updated arrival angle tables from
the ARRL web page.  The ones included with published versions of YTAD were
not as accurate as they should be, and N6BV posted replacements last year.
It's important to superimpose the arrival angle data over the stack
patterns in arriving at the best (compromise) spacing for the stack.
