Locked Mass market loop antennas


 

What most people want is just to buy a radio and have it pick up
the station they want.

It's only tyros like us who will go to the trouble of owning a
radio -and- an add-on antenna.

Had a gentleman come into a TV shop I was working in, looking for
an AM radio with really good reception, as his favorite station was
at the very edge and sometimes disappeared. I looked at what he had
and determined the only way he would get better reception was with
an add-on antenna of some kind, loop or wire. I spent time and
effort researching and buying parts for a tuned loop, specifically
made to look like one of the early wood-framed ones.

In the end he went out and bought some POS AM/FM table radio
because it looked like an old radio, and went with his furniture.
He couldn't pick up his radio station -at- -all- with it, but he
kept it because it looked good with his decor. And he didn't buy
the loop I was building for him, because he decided it wouldn't go
with his furniture.

People like us get satisfaction from hand-building something that
then pulls in stations from very far away. I'm betting there are
quite a few here who've even built their own radio from scratch.
I'm also on the CrystalRadio list, and there are people there who
even build their own tuning capacitors and galena crystals!

Most people just want to hit a button and hear music or their
favorite talk-radio station.

So in the end I think most people would rather pay $20 or $50 more
for a radio than have to buy and lug around even a $5 loop, no
matter how easy to transport it may be.

if
people were more educated about the product, and the product was
priced right. I think, for example, if you had a light weight,
portalbe / collapsible loop that was large enough to really make
a
difference, you could sell it if it was under $5 to people
relocated
from their "home team" city and they could DX their old 50 KW
sports
station. Much more $ than that, and people won't buy.

Steve,

Gotta agree with you on this one. I get people coming in to the store
almost every week wanting to know how they can get better reception
of AM stations on their radio. It's the same ol' thing every time.
They need an antenna but don't want to bother with the "hassle" of
hooking it up... even if it's just 25' of wire tucked between the
carpet and the wall.

Seems like no matter how long or hard we Priests of the Technocracy
preach the unwashed masses simply don't want to be redeemed!

Man, where do you find the time? I mean, HAM, propmaking, electronics,
weird antennas, mad scientisting, moderating...

I need a tutorial from you!

My brain won't stop buzzing. It's hard to wind down and sleep at
night. When I was young and my body could take it, I might stay up for
a couple of days or 3 days (rarely!) in a row. If you only knew how
many projects I have going... I used to read Sci Fi and science
constantly, now it's datasheets and technical lit.

I'm not a Ham, though. Never learned morse code.

Way above AM BCB, but is anyone here making DDRR antennas? Those
horizontal loop, omnidirectional antennas? Direct driven ring radiator?



Found a site for one that does not require a ground plane. It is to
the DDRR above what a vertical 1/2 wave is to a 1/4 whip with ground.



How about microwave patch antennas? How do you feel about allowing the
related topics of radio direction finding and low profile antennas as
on topic subjects?

Steve,

DDRR stands for Directional Discontinuity Ring Radiator. I thought
about building one for 30 meters (and still may) but rejected it at
the time since horizontal space is more of a premium item for me than
vertical space. They have basically the same physical requirements as
MagLoops. Fat conductors, low loss connections, high voltage
capacitors if you're gonna transmit through them. Since they are more
akin to a 1/4 wavelength transmission lines they are probably not as
size tolerant as MagLoops. Haven't tried it, though, so can't really
say.

I'm in favor of discussing just about any kind of compact antenna
here. There's lots of controversy over whether EH, CFA and Capacitive
Disc Antennas work or not. Most of that has to do with inventor's
claims that seem to contradict Maxwell's equations. I don't think
that is very important. Some of the designs look like they may be
very viable solutions for SWLs or folks who are limited to using
indoor antennas.
