Re: [TCML] Is my 10" Tesla Coil Illegal ?

[Andrew Robinson <teslamad@xxxxxxx>]

Sounds like a big coincidence to me. None of those systems should be 
effected by your coil directly. Both your magnetic field and electric 
field will drop off. The energy density is inversely proportional to the 
square of the distance from the source. It would require a very large 
coil to cover a 4 block radius to measure any substantial reading. Now 
feedback into mains, thats a different story. You need to be filtering 
your AC mains, not so much for the sake of your neighbors, but for you 
and all your electronics in you house. TV, Computer, etc they're all at 
risk each time you run your coil. The sound from the coil might set off 
a nearby car alarm (as my truck does) but not a house alarm. Third 
generation garage doors operate in the 300-400 MHz range way above your 
coils operating freq. New garage doors encode and decode messages too 
unlike the first generation which only required a RF signal. If you 
really think its causing all these problems then down size of get 
yourself a big faraday cage. Maybe try a few more tests to see if you 
get the same results. See if you can get some consistent data. I really 
wouldn't be too concerned though. Everyone on this list obviously 
operates a tesla coil. Some safer than others, and its still the "Tesla 
list", not the how to open your neighbors garage or set off their house 
alarm list.


Goodluck
