Hi List,
     The Tesla coil is a fair broadband jammer. However, your 100KHZ Tesla
coil does'nt have much energy at cell phone freqs(about 950MHz). The other
factor to consider is the old "square law". The energy drops at "square" of
the distance. i.e. twice the distance=1/4 the energy.

Later,

P.P.S. I would guess that Gary's coil is propagating a lot of energy through
the power lines. All these motion detectors and alarm systems are poorly(if
at all) filtered/shielded.
