Default Name that antenna

Hiya...

One of my two antennas is a home brew 200 ft random wire antenna. It's well
grounded and also makes use of a coax feed and an ICE-180 matching
transformer. Most importantly, it's set up and folded more like a piece of
modern art rather then an antenna :-). I've had a number of DX'ing friends
over here to check out my R-75 rig and my antennas. A number of times, we
have also had them bring their rigs over here, including an R-8A and a
Kenwood R-5000. We did some side by side comparisons between radios to see
what was the best DX'ing rig. Although we didn't come up with a definitive
answer about what rig was best, we've decided that for reasons unknown, my
200ft "FRANKENSTEIN" random wire antenna was by far the best DX'in antenna
that any of us have used. Still, I have no idea of what the thing is. I
just strung the thing up.. LOL.

Here is a link to the part on my DX'ing page that has comprehensive info on
"FRANKENSTEIN" including diagrams.

Does anyone know what the heck this thing is ??? How would you classify
this antenna besides being a work of modern art ??? LOL. There has got to
be a reason behind it's performance.

Any input would be appreciate.

In short.. What the heck is it ???

recent scientific investigations have found antennas based on a "fractal"
like pattern are better than their more conventional counterparts, but as
far as I know, they have not come up with a reason s.

That sorta resembles an inverted V folded dipole. At 200 feet, I'd bet it is
somewhat directional as well. Good looking design ! I did something similar
once, but had a 20' wooden pole and did it similarly, and it worked well
also. Is it just one long continuous wire, or two equally long halves ?

You sure it wasn't meant to be a patio cover.
The web page is really nice.

Hi Michael:

I've found, that if you put up "More Wire" you get " More Signal".

A John Carr book says if you Quadruple the antenna length to get a 6 DB
( Noteceable) change in signal strength. Found that to be true,

- So it sounds like what you 've got ( 200 foot multi directional ) works
pretty good !

- If you're bored, ( & hanker to terrify the neighbors, )

You COULD try ( using a different color wire to keep it straight ) put up
another 600 feet of wire on your roof

& see if it measurably increases signal strength..!

I mean, if bigger ain't better,
how do you account for Ariciebo or the Very Large Arrays, or Art Bells Huge
Loop antenna?

Antennas are a nice, cheap hobby . . ..

Hiya...

It's one long continuous wire...

Michael:
- Maybe it's just a "BFA" class antenna.

My Wife caught me up on our Apartment house roof, with a measuring tape and the
Jwin JX -M14
-Just checkiing the circumference of the roof..

Antennas are totaly Verbotten.

Promised her I wouldn't do anything until they actually install
a lightning rod array up there.

About once a year we get hit by lightning, totally fries the elevator controls.
Does give one pause...

Bigger is better providing your receiver can handle the greater signal
levels without overloading. If not, you will be frustrated with all the
spurious (false) signals to be found throughout the receiver's tuning
range.

Where's the connection from the antenna to the matching transformer? I
see the end of the wire connected to an insulator on the chimney but
where's the other end (beginning) of the antenna wire that should be
connected to the ICE-180? Also, if the antenna wire is a 200-ft
continuous length, I don't see what path it takes to make the 'X'
pattern. It looks like two seperate doubled wires crossing over the
chimney top but not part of a continuous length of wire. It would be
helpful if you added some arrows to show the path of the wire as you
constructed it.

Michael,

Seems like you have already named your 200 Ft Random Wire Antenna.
- - - So let it be "FRANKENSTEIN" !
- - - "Fran-Xan-Wire" would have been my choice )

Someone with Antenna Modeling Software may be able to give you a
better 'idea' as to the reception pattern that your unique antenna
exhibits.

The Double Folded "X" Shape and the Ground Wire that bisects the field
of "X" creates infinite possibilities.
- - - http://md_dxing.tripod.com/hobbyandhowto/id5.html

IMHO: What makes your "FRANKENSTEIN" Antenna such a performer is that
fact that it uses the Low Noise Antenna design concepts a la "John
Doty".

- - - http://www.anarc.org/naswa/badx/ante..._longwire.html
- - - http://www.hard-core-dx.com/nordicdx...eed/coax2.html

Plus you used the ICE-180 Matching Transformer.
- - - http://www.hard-core-dx.com/nordicdx...ed/ice180.html
- - - http://www.hard-core-dx.com/nordicdx...d/magbal2.html

Add-in the fact that your have a 'good' Grounding System.
