[TowerTalk] XM240 to Moxon

[Pete Smith]

I don't think EZNEC tells you the whole story, in this case - I would 
expect that high yagi to give you much better signals into the West 
Coast by virtue of the lower angle of radiation.  This problem would be 
duck soup for MultiNEC, which combined antenna patterns with propagation 
data and produced coverage maps - too bad it's off the market now.
