It's been hot as heck in NYC for the last couple of days. Yesterday, to
escape the heat, I spent much of the afternoon in Prospect Park,
where's there's usually a nice breeze and cooler temperatures. On a
whim I brought along 100 ft of wire and my HF-150. I laid the wire out
in a 'snake' configuration, right on the ground, and was pretty
impressed with the results. I was in a quiet spot there in the Park.
Even so, when people describe this as a low noise antenna, they aren't
kidding. Using a couple of tree limbs, I raised the wire up about 7-8
ft. The increase in noise was noticeable, and the s/n ratio was a
little worse.

I realize that the classic snake antenna uses coax, not wire. However,
ordinary old insulated wire sure seemed to work well for me yesterday.

I've read around on the web about these antennas and their low noise
characteristics, but I'd be interested to hear about any experiments
the readers of this group have done. I'm especially curious about how
the presence of metal objects in the immediate vicinity of a snake
antenna would affect its performance. For example, suppose you took
200ft of insulated wire and 'stiched' it through the bottow row of
'links' on a very long chain link fence. I can't imagine a stealthier
antenna than this, but would the fence muck things up?

Outstanding!

This is a post that should be shown to every new-poster who asks the
inevitable question, "What kind of antenna should I use?".

Just like , you use whatever you have and rig it up
however you can; then post your results.

It seems at times that folks get so tied up in the technical details, and
trying to *exactly* follow some established design, that they really miss-
out on finding out something new that can work acceptably for their unique
set of conditions.

I say lace that wire through the fence and see what you get. Conventional
wisdom is that you will get Result-A (and you very well may). But, wouldn't
it be interesting if you got Result-X, Y and/or Z?

I expect some of your desired energy will be inductively coupled to
Ground through the fence posts spaced every 10 feet. I further expect
an insulated wire on the ground, not near any other metallic objects
will work better.

I have an instinct...
