The antenna works great. That null is deeeeeep!

I'd like to put it in the rotator I have on the roof. My question now is about the recommended 3-meter height: Would that be from the ground, or from the roof itself?

Thanks for the great antenna design!

from the "ground plane" if the roof and/or its structure are conductive (e.g. concrete and iron) then 3m from roof will be ok
