Re: Random TC Questions

The strike rail should NOT be closed otherwise it will look like a shorted turn and kill the magnetic fields that make the coil work.

You should connect the strike rail to the base of the secondary which in turn is connected to RF ground (and NOT the power cord safety ground) usually a stake in the ground, or a water pipe, etc will work for this.

EMI filter is not necessary for the coil to work. The desirability of it depends on what is the surrounding environment (ie, who or what are you going to interfer with). My 1000 watt coil has yet to have a line filter and does not interfer with the TV when on its own load panel (breaker box) branch.

Hello Folks. I have two random questions:

1. Is an EMI Filter between the NST primary and the power connection
recommended or required? This is a school project.

2. I've seen images of the strike rail having a gap (not connected or
soldered). I read somewhere that there should be a gap so that the
strike rail does not form an inductance which may interfere with the
operation of the primary/secondary magnetic coupling. What happens if I
connect the strike rail and then run that to the ground?

Thanks again!!
