Re: the nature of parabolic reflectors

["Rich Peet" <>]

The things that I am fighting myself with here are:
1. Is it agreed that the size of the focal globe changes with
frequency?
2. Why do I experience a more noticed frequency gain shelf than a
telinga when I am using a more flat and larger dish?
3. Why is the Telinga so much more shrill than my larger dish?
4. How would one measure the pressure difference and size at focus at
various frequencies and at various different origination points?
5. Why does a dish amplify a freqency at 1/8 wavelength?
6. How does a corner reflector work compared to a dish at 1/8
wavelength?
