Re: the nature of parabolic reflectors

["Rich Peet" <>]

You are getting there for sound Raimund.
Now you need to figure where the lowest freq that the "song" birds
sing.
Then you have to figure the usable width of the focus globe of a
parabola without loss of gain v. freq.  Then you can decide for
yourself if their is an advantage to adding in part of the curve as a
corner reflector.  And myself just for the sound I still wish to
build it out of graphite comp. and not polyc.  Some day in the not to
distant future maybe I can build one.

But this spring is surround for me.
