OK, a quick post and then thats it for being off topic!
The Fibonacci Sequence, as applied here, is basically a non-resonant spacing of elements. If I have two antennas in or near the same band that needs to be placed on top of a vehicle (news van, government, etc) I take the 1/4 wavelength of that band and multiply 1.618 to get my new spacing.
Example: VHF = 17"
17 * 1.618 = 27.506"
I place the second antenna 27.5" away from the first and my in band interference practically goes away! No, its not perfect and again, I would have a hard time using theory to prove it, but it works for me. Try it.
If its two separate bands, I average the two frequencies, divide by 2 and multiply by 1.618.
I know, snake oil! I would agree, except for the part that it appears to work.
This HAS been proven in sound rooms however. The BEST dimensions for a sound room is 16' wide by 26' long, with a 10' ceiling. (16 * 1.618 = 25.888 and 10 * 1.618 = 16.18). This room becomes non-resonant for all frequencies.
This formula has also been applied to architecture and has been found to supply the strongest support structure. You also see it in nature like in the chambers of a Nautilus shell. I didn't make this up!
Disney produced a film called "Donald goes to Mathmagic Land" where this phenomenon was discussed.
Its FM!!!
