Re: [TCML] Treating RF feedback

Hi All,

With the renovation of my coil nearly complete, I'll need to address the
old issue of electrical appliances going haywire whenever I run my coil.
At the time I didn't have a proper RF ground, only a counterpoise.

How big is your counterpoise?  It should be more than sufficient.
you don't need a "ground rod into the soil" for an RF ground..(after all, people run coils in buildings on not the ground floor)


On
separate occasions, I'd have the jacuzzi tub turning on or the sprinkler
system switching the sprinkler heads like pinball paddles. My hunch was RF
interference which the list seemed to support.

yes, but most likely coupled back through your AC powerline.. Filtering of the powerline is critical.

So is making sure you don't have a "receiver loop" in the victim circuit (sprinkler systems and garagedoor openers are notoriously bad, because they've got wires running all over the place, and aren't particularly RFI insensitive)



I'm currently attempting to install a 10' ground rod but that's proving
difficult with my dry rocky soil. Since my deadline is fast approaching I
may need to rely on the counterpoise once again and I want to make sure I
don't go fizzling all the fancy electronics we've acquired in the past
years since I retired my coil.


I wouldn't bother with a ground rod.


On a separate topic, any bright ideas on getting a 3/4" copper pipe backed
with city water pressure through a boulder?


See above..

Work on having a good grounding mesh right under your coil and making sure that anything that sparks reach out and touch is connected to that mesh, and that the mesh is connected to the bottom of the secondary.


Thanks,
Brandon H.
