I can get a clue on how well it works from an NEC2 model. However,
this loop is easy. Remember your complaints about the relative merits
of a circular loop, octagonal loop, square, and triangular loop? Well,
this contrivance is a good example of a very shrunken loop, where the
area enclosed by the loop has been minimized.

That is an assumption since you are analyzing it as a simple, circular
loop which it is not. NEC2 may or may not be adequate to model it.
Someone posted that they get significantly different results from two
different simulators under some conditions.


Anyway, I'm a big fan of building something just to see what happens.
It's part of "Learn by Destroying".

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.

Yep. I also read the reviews on various products and usually find a
few fanatics that will defend inferior junk to the death. It happens.
However, I'm not talking about "these" antennas as in all types of
loop antennas. I'm talking about this particular loop:

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?

I'm Jewish and occasionally wear a yarmulke (keepah or skull cap)
which entitles me to some liberties in their design and operation.
Full disclosu Mine is not lined with tin foil.

I'm referring to the Pastafarians of which I am a member.


Argh... I'm late again.

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

Actually, I try to always be on time or a little early. In this case,
it was for a ritual morning exercise trudge through the local state
park. We usually have a small group that I didn't want to keep
waiting.

I mean "late as in *the late* Dentarthurdent".
