Topband: Vertical dipoles in the real world

[Bob K6UJ]

Jim,

I'm very interested in your experience with vertical vs horiz dipoles for 40 meters.  I have a  similar situation in the works.
I am using a vertical dipole for 40 meters with the top attached to a 3 foot side arm at the 95 foot level on my tower.
It slopes away from the tower about the tower about 15 degrees.   It works pretty well for dx but I think the noise level 
would be improved with a horizontal dipole.  I am planning on putting a rotatable dipole for 40 at about 3 feet above the 
top of the vertical dipole and see how it does.  I'm hoping more gain and quieter receive.
