Yes indeed! In an urban invironment that is especially important. I`ve
fought the battle to suppress ghosting and smearing. But, my signal
sources were nearly horizontal and they reflected like billiard balls
from every reflective object they encountered. Reflections were often in
the horizontal plane same as the incident signal.

I would think that shortly after a satellite makes it above the horizon,
the incudent wave`s reflected signals would be headed skyward and be
unlikely to cause much trouble at the receiver. The quadrafilar helix
pattern appears something like a mushroom.

I only recently got it. Now I think it is unfortunate I didn`t have it
on order before it was released. It is crammed with good stuff.

Congratulations! Hope you enjoy it as much as I. His catalog pf various
antennas is without par. His theory is systematic and concise. He must
have been a tremendous asset at Bell Labs.
