And I've proven to myself that an open wire loop can be just as
good as a "shielded loop" just as long as balance is taken care
of. It's the balance that matters. If the two types are equally
balanced, and the same size, they will act the same.

Sooo, in shielded loop the shield is the antenna according to W8JI and
worshippers. But you take the shield (W8JI antenna) away, now the wires are
antenna, some say don't need no stinkin' shield and "antenna" to work as an
antenna.


The rest is just fodder for bored old farts on a newsgroup.
Of course, many won't agree with me, and this would include Yuri,
since he believes a shielded loop is quieter than an open loop.
But I don't care.

Amazing how selective in reading and digestion of postings some people are.
They tend to ignore the reality and description of it, they pick on
selective "proof" of what they were taught and figered out.
I emphasize, that electrostatic shield on the loop antenna is effective on
close proximity radiation, within some fractions of a wavelength from the
source of interference/signal. It does not (significantly) affect band noise
or distant noise/signals. Anyone who can build shielded loop and test it
within local arcing source or test transmitter, can see the attenuation of
the said noise.
So shield works as a electrostatic shield, if you guys like it or not, or
refuse to admit.
It is not that I believe in that, I have experienced it, seen it, measured
it and it works, it is there and anoyne can verify that, contrary to
"theories" of those who "figured" it can't be.
Electrostatic shields work on principle of capacitance plate, being grounded
and side exposed to electrical/electrostatic fields shunting the field to
ground. Capacitor's one "plate" is the interference/signal source
(antenna) - other "plate" is the el. static loop shield, grounded, shunting
electrical fields to ground and preventing from entering the antenna.
(Something like that).

Sooo, antenna works without shield (not just my assertion), but when you
insert it in the shield then shield becomes W8JI antenna. So his shield,
untuned becomes antenna, but my tuned and tunable inside the shield antenna
is not the antenna? Makes as much sense as "there is equal current along the
loading coil doesn't matter what", riiiiight?


It's a free country. Or I think it is... Sometimes I wonder these days
with all these goofballs we have in DC running the show.

We were better off with Clintonistas having orgies in WH while Bin Ladin
turbanites were running around, blowing up Americans and using our flight
schools, our planes to demonstrate their "religion of peace" in NYC WTC
inferno?

Let's stick to some reality in antennas.
