In QST sometime in the last 3 or 4 months there was an EXCELLENT article
that showed how to put down the most efficient radial system for any given
length of wire you have available. It's based on the famous Brown study, and
I found it to be one of the quickest and most efficient ways to practically
determine how to lay out your radial field for a ground mounted vertical.
For some reason, I haven't seen it mentioned....and it is based on the best
empirical study ever done on radials for ground mounted verticals. I wrote
the equation into a simple (one cell) excel spreadsheet, and by simply
inputting how much wire you had available to bury, it reveals the number and
length of radials that will produce the least ground loss. (The equation is
clearly displayed in the first few paragraphs of the article.)
The article has a lot more info in it, including graphs to give you a feel
for the actual losses involved and recommendations at the end. That single
equation, however, makes reading the entire article well worth the trouble.
