I don't get your point here.


1. It's not a fractal.
2. It's more like art than science.
3. It's a variation on my dryer vent hose antenna (tune by pounding).
4. It maximizes most of the worst characteristics of a loop, such as
high length to surface area = low Q, small capture area, and optimized
for low VSWR.
5. If you're worried about temperature drift, the lack of rigidity
should make it drift even more.


But you don't really know the details of how it works, so you don't know
how well it can work other than by building it and testing. I haven't
seen any reports that can be considered rigorous, but there is plenty of
enthusiasm by the users. They think these antennas work well.


Build one, monitor your dreams.


My ego is too inflated to fit into the loop. I'll stick with the
traditional colander on the head arrangement:

Are you making fun of religion now?


Jeff, I don't like the parallel sections,
seems like it could be made more complicated
using x, y, and z right angles. Nap on that! :-)

Sorry, but everything I've built that involves a 4th dimension has
dissapeared when I applied power. The fields cancel and the entire
antenna is sucked into the resultant vortex.

Argh... I'm late again.


Someday you'll be late for the last time and everyone will call you "late".
