Hello again Lou,
I hope you do not mind me picking your brain about the Titan.
I am rethinking mounting on roof for the reasons you mentioned. But now I
have other questions.
Since we have a dog I would rather not do a ground mounting.
I have a shed at the back of yard and am thinking about mounting a mast on
side and mounting antenna. How high of the ground would it have to be so the
four counterpoise would high enough to be out of reach.
