"A fractal antenna's response differs markedly from traditional antenna designs, in that it is capable of operating with good-to-excellent performance at many different frequencies simultaneously. Normally standard antennas have to be "cut" for the frequency for which they are to be usedand thus the standard antennas only work well at that frequency. This makes the fractal antenna an excellent design for wideband and multiband applications."

1. Log periodics have the same broadbandedness...

....and gain over a dipole to boot.

2. digital signal seems to degrade so quickly with interference. Would either application help with

this problem?

3. Then why are all log periodic tuned to only one band or narrow range of frequencies?

Log periodic don't work very well for wide band.

6. Those are mostly Yagis that are narrow band..

A Yagi and an LPDA look rather similar to the untrained eye but work on different principles.

LPDAs can be quite broadband, the usually cover the VHF TV channels with one antenna.

8. A well designed L-P can cover an octave...

...50-100 MHz, e.g. -- you're thinking of a Yagi? They're cut to one frequency.

4. Rhombic antennas are even better and have more gain.

For VHF and UHF rhombics don't have to be huge, LPDAs are pretty damn big at low frequencies too.

5. Interesting, but I get all of my stations fine with the antenna I've had for years.

I've got no complaints and my digital reception is excellent.

7. Oooh cool! Now I can use that Voronoi diagram technique to come up with a fractal tiling!

And the kids ask "when are we ever going to use this". lol!
