What about putting a skylight high on the roof and putting the antenna up in 
it?

What's magic about inside vs outside the roof/skylight envelope?

I have a large pine tree out front.  It's roughly 3x the height of my (one 
story) house.  What are the chances of any lightning hitting my house rather 
than the tree?  What if I put an antenna on the top of my house so the tree 
is only 2x the height of my antenna?

Of course, that depends on how far the tree is from my house.  Not far.  Call 
it 45 degrees from the back of my house to the top of the tree.  An antenna 
on the top of my house would probably be below that sight line.

Is there a good book or URL on lightning vs antennas?  Again, I'm interested 
in both the technical issues as well as the local zoning/legal issues.
