[wxqc] Pole for wind gauge

[Richard]

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.
