The best thing to do is not tell the neighbors that you have a Tesla Coil.
If someone has interference they won't know who to complain to if they don't
know who is doing it. I don't think there is much you can do about the
problem. All sparks produce interference. Car Radios are specially designed
to filter out interference from the igniton system. If you charge up a
capacitor and discharge it in the same room with a TV, O-Scope or radio you
will see the discharge interference on the TV screen, O-Scope screen or hear
in on the radio. Lighting from thunderstorms produces the same interference.
No RF in a thunderstorm. When I run my 10" coil it sets off house alarm
systems 3 blocks away in my neighbor hood, makes automatically lights come
on 1 block away, and produces some snow on my TV screen. Its a lot less of
a problem than the Amateur Radio operator that use to live over on the next
street. No one could watch TV from 4 pm to 10 pm every night for over 2
years. I got cable TV because of him and still got interference from him on
the cable. Everyone in the neighor hood complained to the FCC and they did
nothing about him. Finally one day on my way to work I had to drive around
his Amateur Radio Antenna which was laying twisted and bent in the middle of
the city street where someone had pulled it down in the middle of the night
with a car, truck or something. He never put the antenna up again and moved
away about 6 months later. Short runs on the TC doesn't cause much of a
problem anyway.
