Some years ago experiments have be done using trees as antennas. Where
can I find references about ? Do fellows here known about the results ?

Claude

hi claude,

since trees have a lot of water in them, they do not make good antennas.

joyce.

they are fractal, I think someone might sue you for infringement.

Yes; I knew when I made rocks and trees into antennas I was going to get
some flack.
which served ego rather more than technical discussion.

This thread still remains as one of the most comic pieces published in
this group and worth reading the 59 entries. Where the comedy lapses
into technical content (rare), it provides specific information about
plants and RF interaction. I am glad to have run into specific
conductivities comparisons showing how the vaunted "conductivity" of
sea water is 200000 times worse than nichrome (or 10000000 times worse
than copper).

This one was not the only thread confined to this topic, but I would
wager all the rest amount to tedious repetition of the usual
population count of angels on a pin-head.

Hello Chip;

I suggest you back off on this W8JITom fellow. He seems to make things
up
that you didn't say and refuses to try something as simple as knocking
a
nail into a tree. Perhaps he lacks the coax cable. I will turn the
filter
back on. Might do well for you to ignore all his responses as few seem
worthwhile.

People have been using trees for clandestine antennas since before
WWII.
As you point out it is not the best of antennas. For him to deny it is
at
least consistent for him.

As for your comment on libraries I heartily commend it. Everyone has
to
keep up if he is an engineer worth his salt. I remember going out of
my
way to get to Tech's library several times a year even when I lived
300
miles away.

Best to You and others here;

Jack

How about a couple of Pole Beans fed from the middle, as they grow you can
tune longer bands.

By hearsay and legend -- In W W 1, an Army Field manual recommended feeding
a tree for an antenna when the real antennas were shot down.

Since I am not aware of any 50 ohm trees (hi-hi), probably use ladder line
and a tuner.

And remember, as an old timer discovered when he loaded his bed springs ---
RF GOTTA GO SOMEWHERE

Let us know which trees worked best (:-)

Yeah, kudzu could have some advantages. Lots of it available, and
you'd probably end up with a dense-fractal design.

It'd have the disadvantage of de-tuning itself every day or so, due to
the rapid growth, unless you transmit with enough power to burn off
the growing tips. Lends a new meaning to "pruning your antenna".

The three rules of growing kudzu:

- Although it's capable of growing on solid concrete, it'll do
somewhat better if there's at least a little soil in the mix.

- Always plant kudzu at night, by the dark of the moon. Otherwise,
your neighbors might figure out what you're doing, and start
throwing rocks at you.

- Fertilization is not required. However, the kutzu vines will
definitely appreciate having the bottoms of the smaller leaves
lubricated with 10W40 motor oil - this reduces abrasion and chafing
when the vines grow rapidly across the ground.
