RE: [TCML] Grounding rods

[Mike Thompson <mthompson14@xxxxxxxxx>]

Well I have in the past run a comparison between receiving the signal from Cutler Maine, @ 24Khz with a tuned loop and a ground electrode. The loop was basically a 4 foot diamond shape using 4 conductor phone line tuned with a capacitor decade box. The ground electrode won hands down on performance and noise rejection. This was in wet Florida soil. Up here in New Jersey the hard clay doesn't seem to like ground electrodes. 
 
An RF ground for a Tesla Coil would be only one use for the pair of electrodes I would like to plant in front of my garage :)

The short answer is, no, I haven't tried using a chemical ground.

The problem is, I'm unaware of any means to gauge the "goodness" of a ground system.  The truth is, the spark performance of a Tesla coil is relatively (maybe completely) unaffected by the quality of an RF ground system.  What IS affected is the degree to which RF and HV transients are coupled into one's mains wiring, but again, I'm unaware of any means to measure or compare mains corruption.

If you can detect a performance difference with different grounds in receiving VLF radio, you may be able to teach us something!
