Ok. I found a TV antenna. It's one of those that are just a
sort of a stick that you can expand. The connector is the
normal sort of like an audio cable thing, only slightly
larger (meaning it will only hang loosely on an audio
connector).

I tried just connecting it to the audio in first on my mixer
and thereafter on my soundcard, but neither of these
experiments yielded any results, not even when I was
touching it (which, on normal audio cables, produces a
sound, as you may know), and this leads me to my question:
Shouldn't there at least be sound when I do that? Or
is it something about the cable's resistance/ohm thingie or
something? I mean, even if it is a bit loose, there
has to be a connection in there, and I would expect there to
be at least some sound, if even only when I jiggle it
around when connecting it, but in both cases there was
nothing.

Is there anything I can do to make it so that I can receive
the radio signals as audio signals, or possibly even to
somehow output audio in a sort of an effect loop, then run
it through the antenna, and then back to the mixer for any
possible effect this may have?

Try it on your Tandberg and record directly to tape... Just
brainstorming here, really...

Ok, at least now I have a result, but I had to use a normal
audio cable with a jack on the end (so I still didn't get
any sound when connecting the antenna directly), and the
result wasn't really different from what you get when you
just put your finger on the tip.. I was expecting
something.. different, but this is an extremely uneducated
guess...

Not to be condecending or anything, but learn something
about radio first! There is a reason antennae transmit radio
at non audio frequencies!

Go and read how an AM radio works and you will hopefully
understand something. You need to realise the length of the
aerial is inversly proportional to the frequency being
transmitted.

I guess you could try to convert it into a Theremin or
something.
A bit of googling is required.

Yeah, I was really more interested in making it into
something like a theremin, although not quite. I figured I
could achieve some sort of effect by simply sending an audio
signal out through a cable that I just held up to the
antenna, and then that signal could possibly flow through
the antenna and then, possibly, with varying lengths of it
extended, I could do something. It was just a dream by a
little boy, don't worry.
