While this provide some details regarding your antenna, it is not sufficient
for me to visualize it.

If one can't visualize what you are talking about, getting help with your
questions will be difficult.

You could try a simple experiment: Remove the active part of your antenna
and replace it with a dummy load. Leave the reflector/dish/whatever in
place. If you still pick up signals, then the antenna itself may not be the
problem.

By 'active part', I mean the helix antenna.

You have a web site, a link to a picture would help me understand what you
are doing.
