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 . . ..

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 :-).


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 ???

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.

Have you also noticed there is a 6dB increase in noise?
The only way to get increased sugnal strength for horizontal antennas ( i.e.
S/N) is to make the antenna directional- so there is an increase in one direction
at the expense of another direction. Not very useful unless you can rotate the
array.
