I live in southern Oregon on a level 2.4 acre lot.  Have quite a few trees in 
the 70 to 80 foot high range.  They include ponderosa and sugar pine, white 
pine and Douglas firs.  Am considering a tower for a yagi or quad and as a 
support for wire antennas and am wondering how tall the tower would need to be 
to avoid serious absorption of RF.

Soil here is full of fist-sized rocks with clay ... and dries out in the hot 

Also, a few miles away is a mid-sized mountain which is east of my site.  I 
used a topo map to determine that the top of the mountain forms an angle about 
15 degrees above the horizon.  Is this high enough to be a concern?

Thanks for your input.

Jim, W7PUP
