A spectrum analizer can find your tesla coil. My cousin works for the
department of defence and is stationed in Germany. His jop involves keeping
several spectrum analizers and receiver stations in full operation. The
systems are used to spy on foreign countries. He told me that the spectrum
analizers looks at all frequencies and a computer records the information
over a period of several weeks. Then if one day a new frequency appears on
the spectrum analizer all receivers are tuned in on that frequency.
Directional vector antenna are used from each receiver to pin point the
exact
location on the transmition. The government is interested in listening to
any frequency that wasn't there before. The way foreign powers try to keep
things secret is to change the frequency of the transmitter each time they
use it. My cousin does not approve of my tesla coil. He says they are very
bad but refused to say much more. He is the CIA type that thinks everything
is either BLACK or WHITE and there should be nothing in between. My cousin
did not say anything about receiver stations of this type in this country
but
it wouldn't surprise me at all if there are some. I would think that unless
someone complains or your Tesla Coil interfers with something like the
airport or police etc. you don't have anything to worry about. It would
probably be wise to keep the existance of a tesla coil a secret so neighbors
done know where the TV interferance is comming from.

A Tesla coil properly designed and constructed, with line filters, separate
grounds, etc. will not transmit much RF when sparking. If you load it up
with a big toroid so it cannot break out and run it, it will act like a
transmitter. My coil running at 7 kva barely causes snow on my own TV.
