Right on Tom,
I once had an H frame for my stack of 4 M2 six meter 40 ft. boom yagis
which worked great for EME. For terrestrial work it was really too
narrow. To give an idea, if I had a signal 56 above an s0 noise level
with the beam peaked, all I had to do was move the rotator 5 degrees and
you could not even tell the signal was in there! I missed lots of QSO's
because I wasn't aimed properly. Now I have those 4 antennas stacked
vertically and the forward lobe is broad enough to be useable.
