I 've read a lot of articles over the years about ground systems and how to build a good one. Most of them ignore actual soil conditions and few talk about the differences between "DC/AC (Low Freq)/L
N0AX's ARRL book on the topic is excellent. Also, these two links may help. The first addresses grounding and bonding, the second about radial/countepoise systems for verticals. http://k9yc.com/Groun
I might add that the Kindle version of N0AX's book is available on Amazon for only $9.99. The Kindle version is pretty cool because you can click on hyperlinks and look at them easily. If you don't

That would be the new Second edition, shipping at the end of the month. Or do you drive a Delorean with the flux capacitor option? 73, Jack, W6FB _______________________________________________ _____

So I will say it AGAIN. What I want to do is measure the ground resistance of a multi ground rod system in VERY POOR soils in my case. WHY I want to know this number or what I intend to use it for IS

Not just UHF, lots of VHF and HF. Worked for them for twenty years. Leaf through the book, you might learn something. Sent from my iPad _______________________________________________ _______________
Dave, To determine your worst case ground resistance, youll want to get ahold of a local geotechnical engineer and ask them to come do it for you. Youll want it done during the driest time of the yea
