Two sticks, one vertical, the other horizontal placed along the path of the
shadow at high noon will show True North...

HEY!!! Did I hear someone asking how to determine "True North"?!?!?!?!?  It
was kinda hard to hear over the S-9 Hoot Owl thread and +20 dB generator
noise right now... :-)

As everyone knows, there's been enough threads regarding finding "True
North" to weave a fine pair of socks... But that aside, you can use Goggle
Earth to determine "that direction" using their tool to zoom into any
location in question. The map defaults to N/S orientation.

I verified my antenna alignment by picking a known object a half mile away
from my tower. In my case it happens to be the east side of a church down
the road. Not all areas on earth have been mapped with high resolution yet,
so this technique might not work for everyone.

Credit goes to my late father who taught me this "lining up" technique when
we were fishing on Mille Lacs Lake (about 27 miles across) locating specific
fishing spots. This in the 1950's, way before GPS.

Try the above link to work out your Declination, there is a link on the
site to a calculator.  I doubt you would be as much as 30 degrees off
true north, I am 18 degrees here by SFO.
