Smile Slinkey Antenna

Has anyone used a slinkey antenna? I bought one and hooked it to a tree in my yard about 30 ft up. I have a Grundig Yacht Boy 400 and I clipped it to the telescopic antenna. I dont see much improvement. Live in the Wa. state, is recption real bad here or should I update and get a newer radio? this one I bought new in 91.

Thanks,

Clyde

Hi Clyde,

That sounds like plenty of antenna for most SWLing - there's just not
enough sunspots to hook it too. A new radio won't fix that.

To those who are counting those sunspots (the missing ones), they have
theories about that which also involve the freemasons, ancient
astronauts, and other influences that will converge on a solution in
2012. The short explanation is that "time will tell."

I'd heard quirks in the solar "jet stream" so to speak..

It's soot from the sun.

The antenna sold today as a "slinky" is not the slinky of old as shown
in Jasik's book.
If one is to put a lumped load into the schematics of an antenna then
one MUST add a cancellation to the structure as the intent for maximum
efficiency of radiation is the correct use of distributed loads only.
The present day slinky consists of continuous length of wound
inductance or a "lumped" load. The true slinky consists of equal
amounts of clockwise and clockwise turns such that the lumped
inductance is canceled leaving only distributed loads.

O.T
As far as the "soot" term being presently bandied around, it is an
adjective which describes the chemical effects of combustion. Only
those old in the tooth or unfamilier with physics describe it solely
as a product of burning coaland nothing else!
This is similar to the use of "waves" in physics with respect to
particles. One is a noun,
where the other is a adjective that describes the action of same.

Default Slinkey Antenna

It's poor grade of Metal has a HIGH-RF Resistance. Unlike COPPER wire,

Those SLINKY Antennas, Get very WARM almost HOT, so you really
know they do work, but very very inefficient.

Like trying to Pump at 200 WATT STEREO into your electric shaver
or light bulb!!!.

If they were pure Copper, you'd have something to talk-About!

Try making a QSO on a Bed Spring VERSUS a Dipole or Loop antenna.

Same analogy........

Except that he wanted to use it for receive only.
