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.
