I probably should have made this point earlier, but working to this level
of precision is pointless for HF antennas, typically with 1/2 power
beamwidths of 30 degrees or more. That's why I hoped we could avoid
resurrecting the True North thread again.
for those who really must know more, go to www.contesting.com, look in the
left margin for the "List Search" window, and enter the terms towertalk and
true north. I guarantee your thirst for knowledge will be sated!
