Topband: Effects of trees

[Tom Rauch]

The impedance of my 160 meter vertical 50 feet or less from 
a few large pecan trees was about 5-10 ohms higher than the 
impedance of identical verticals in open pasture.

The impedance of that vertical went down when two trees 
nearest the vertical were removed.

I have no idea how that changes the FS, but since a tree is 
lossy (compared to a steel or metal structure) it probably 
isn't helpful. By the way, my 300 foot tall tower 400 feet 
or so from the 160 array affects the pattern quite a bit 
when it isn't detuned. It doesn't add loss, it just changes 
where the power goes.
