[wxqc] Pole for wind gauge

[Ken Whelan]

Thinwall electrical conduit works great for this application.   It is
lightweight and strong and very cheap.  I used 1 1/2" for my application
and it worked fine.

I would stay away from PVC pipe even if it is guyed, as it deteriorates
over time. I had a wire HF antenna on a PVC mast (guyed), and a forty
mile an hour gust broke it, leaving the pieces laying in our back yard.
Most of the time I use chain link fence top rails to get stuff in the
air, but I thought I could get away with PVC this time. Properly guyed,
those galvanized steel tubes seem to hold up well, and don't sway in the
wind.

My Vantage Pro2 is on a short mast located on the peak of my roof, which
was the best way I could find to get it up high enough to mostly clear
the nearby trees, yet be accessible. I thought temperature accuracy
would be a problem, but it seems not, as my station appears to track
well with other stations in the area.

If Houston is the recipient of a hurricane's attentions, most of your
instrumentation is likely to be in either another neighborhood... or
another county:-)

One consideration when using PVC for anemometry mounting is the
flexibility of the tubing can cause some problems.

I opted for Linux a long time ago.  I can use it on a variety of
devices, but that's all I'll say.  No need to incite a flamewar over OS
religions.
