[TowerTalk] Arrival angles and sunspot number

[Pete Smith]

The arrival angle tables calculated by N6BV and included with the Antenna
Book and YT are averaged over the full range of sunsport numbers and times
of year.  does anyone know if there is a systematic variation in these
angles with sunspot number?  In other words, during a peak should these
numbers be systematically biased in a particular direction -- for example,
is there relatively more high-angle propagation over a given path under
high-sunspot conditions?  Are such generalizations possible, if only on a
band-by-band basis?  I don't have a copy of "All the Right Angles," which I
assume has the raw data, but I'm hoping someone has already researched this.

I'm looking for the answer in connection with a possible new way of
evaluating antennas that I'm developing.

Thanks for comments.
