This seems like a good place to insert a discussion about a
"shielded loop" being a myth for anything except for deeper

It is a good example of why I do not read rec.radio.amateur.antenna.
Anything you read in it has about a 50% chance of being correct. It is
up to you to figure out which is right. If I want to read a thesis, I'll
crack a textbook where I stand a better chance of not being misled. With
technical articles, I also do not have to deal with terms like, myth,
oldwives tails, or requests for citations and the like.

And r.r.s differs from this how? They spread just as much crap here,
as they do there....Probably more...And much more OT's and radio
whacko's to boot...BTW, I happen to agree with the "thesis". I don't
believe in "low noise" antennas. Anyone who believes a shielded loop
is "quieter" than a non shielded loop needs a reality check. So in
that, I'm glad he posted the "thesis". Old wives tales need to be shot
down.....Over and over...Until dead. :( BTW, I don't have a cessna
citation, so they will be out of luck in that dept...I do fly a lear
31a on my simulator a lot though. MK

Well, OK there is just as much crap here but the posts in RRS do not
usually turn into a "thesis" or degenerate into soap operatic techno
babble with the usual cast of characters.

Generally, the air of pretense does not exist in RRS, as people here do
not claim to be other than nonprofessional on the subject.

Oh yeah and you are wrong about the shielded loop.

I am a professional shortwave listener, as my mother once gave me a dime

No wonder twelve years of inspections found NOTHING.

What a lot of whining. Is this another episode of "As the World DXs?"

Where was the technobabble? It made sense to me...

Well, some on rraa *are* professionals. But again, many are not. I am
not. My work has nothing at all to do with radio, antennas...

Oh yeah and you are wrong about the shielded loop.


Oh yeah? Prove it. I've built both, and tested both, and I couldn't
tell a lick of difference. I have also used both shielded loops and
plain wire loops for the "coupling" loop that feeds a regular wire
loop. Again, no difference in noise pickup.
None whatsoever. If I am wrong, why don't I see the results? I'm not
just barking at the moon. I've built and compared both types just to
test this exact theory. Both of my present loops are now plain wire.
Don't you think that if there were really an advantage to a shielded
loop, I would be using them? My mama didn't raise a total fool. If I
see something that works according to common lore, I'll say so. If it
doesn't , I'll say that too...So far, I haven't seen it...
It's still my opinion that the shielded loops *do* help ensure balance
in feeding, but as far as a magical "anti noise" property, I don't see
it. If you feed the plain wire loop in a manner that also ensures the
same balance, both antennas will respond to any noise in the same
manner. You can disagree, which is fine, but until I see proof of this
magical anti noise property in real life, I will continue to claim the
*lower noise with a shielded loop theory* is a bunch of malarky... MK

Well it did not make sense to me. One thing was said and then the
contrary was stated, then the the one sided discussion went off on
another tangent and then on to some thing else. The thread read like a
voyage of discovery and was not unlike babbling.

No, I'm not proving basic theory and design to you over Usenet. This is
the wrong newsgroup for that. Go play in rec.radio.amateur.antenna

Besides you have have already stated experimental results contrary to
basic theory and practice to your own satisfaction. How am I going to
challenge that?

Sorry Markey I'm not playing rec.radio.amateur.antenna game. Go play
with the other "Professional Trolls."

Hi Mark,

This presents much the situation that W. C. Fields offered when he
stated "I've got the Bull by the Tail, and I am facing the problem."

The fellow hasn't the high beams to switch off cross-posting. Let
this Tritonic Minnow rule his puddle.

Actually, Mark is right. For small loops it shouldn't make any
difference according to the theory in the Antenna Engineering
Handbook. Shielding larger loops may help deepen the null, which
is good for direction finding, but it isn't supposed to do anything
for small loops.

rec.radio.shortwave is the wrong ng for an antenna related debate????
And we are talking about a receive antenna used by many MWL's, not one
used by hams for transmitting. Wrong NG???
****, all that off topic crap must have warped your frigging brain....
I guess if it ain't off topic, or written by some ignorant SOB that
just wants to stir up controversy about Bush/Kerry "dumb and dumber",
it don't belong....Get a grip...

By providing contrasting experimemental results or data... How else???
Are you presently under experimental medication, or are you normally
this slow?


Sorry Markey I'm not playing rec.radio.amateur.antenna game. Go play

Well, Telley, I take this to mean you can't provide contrasting
results or data to refute my claims...Fine. Go play with yourself
then. But every time I see you cut down rraa for no good reason, as
you have seen you do a few times recently, I'm gonna jump your ass
like stink on a turd. If you can't take the heat, keep out of the
kitchen. No one has a gun to your head, making you read certain posts,
even if crossposted. And if you disagree with someones "thesis", why
don't you just provide contrasting data or results to refute his
claims. Seems it would be more useful that acting like a jackass, and
calling him a troll, thesis writer, or whatever goofball tag you want
to attach. MK
