Series of QEX articles on ground system experiments

Last year I posted results from a series of experiments on ground systems for vertical antennas.  That series of reports was converted with some modifications into a series of seven articles in QEX magazine.  The ARRL has kindly given me permission to post .pdf files of these seven articles for those who do not have access to QEX.  Here they are:

Download QEX ground systems part 2

Download QEX ground systems part 3

Download QEX ground systems part 4

Download QEX ground systems part 5

Download QEX ground systems part 6

Download QEX ground systems part 7

A summary of these articles was published in QST for March 2010, pp. 30-33. 

In QEX for May/June 2010 letters to the editor I made the following comments.  "I think too many people are taking the QST article as gospel when it should be viewed only as an interesting set of expriments which shed some light on a few questions.  Even the QEX series, which is much more detailed, raises far more questons than it answers.  I was really hoping to encourage others to expand on my work (as I expanded on Sevick's) by showing how it might be done.  73, Rudy N6LF"

Hello Rudy
Thank you very much for publishing your excellent articles on Ground Systems. They are just what I have been looking for.

Very interseting & useful information Rudy.

It must have taken some considerable time to carry out all of the experiments and write it all up.

Thanks a bunch!

Extremely useful series of articles! My only wish is that something was done comparing elevated radials at > 1/4 wl from physical ground against elevated radials at < 1/4 wl from physical ground. Does it make a difference due to ground coupling?

Hi Rudy,

Your papers about ground arrangement of HF verticals and the influence of radials and their relative position as well as length, were the information I was looking for so long. Thank you very much for those essential info your provide to the HAM community. I will contact you in the future to ask you some question about an arrangement I am planning for my home.

Thanks again!!! Keep up the excellent job.

Many Tks for the series of articles. They are very useful.
However have a question: What happens if instead of Radials, I bury over an area rows of iron fences?
How large has the area to be for a multiband antenna?
Thanks again
