Nice analysis, Dan.

Another feature to think about:  Wind load can be reduced during high wind
conditions by switching to 6 meters.  Does anyone know of an anemometer with
an adjustable alarm setpoint for relay switching at a preset wind speed?

I've been thinking hard about the new SteppIR 4 element yagi
for my station in Boonville.  I did a bit of quick analysis
of the antenna, and wrote it up on my website.  If you have
any interest, go to http://www.k6if.com/ and click on the
link to the article.

Executive Summary:  The SteppIR 4 element yagi on a 32 foot
boom is a very attractive alternative for contesters looking
for a high performance tri-band yagi.  Performance is
excellent on 10 and 15 meters, and quite good on 20 meters
as well.  The only downsides are the price (which is high)
and the possibility of mechanical issues with the variable
length elements.

Best 73,
