Re: No Stupid Questions, right? (focal point)



I asked what part of a 3.25 turn helix should be at the focal point should
be at the focus of a parabolic dish a few months ago.  It was suggested that
the focus should be at the end of turn 1 of the helix.  But in the next
sentence, it was suggested to experiment by moving the helix through the
focus while listening to a signal generator.
