Other than locating an antenna as high as posible and in open space, are there
"sweet spots" that behave like funnels for radio waves? By moving a portable
receiver around to find the strongest signal, I have noticed that certain
locations (I'm talking feet and yards, not miles) produce much more signal
strength than others. Of course, I also end up moving the antenna angle too
which may be responsible for this behavior. Just wondering if this effect is
worth considering when installing an antenna. Or am I just finding the
strongest lobe of the antenna pattern?
