Elevated grounds systems are frequently used in place of wires on or in the ground under a vertical. This kind of ground system can work very well but when there are only a few radials in the elevated system it can be very sensitive to asymmetries in the radial fan, nearby conductors, etc. Here is an article which was published in the March/April and May/June 2012 issues of QEX magazine which takes a much closer look at elevated ground systems than has been done in the past. In the end the advice is very simple: use more radials! This is the same advice I give for systems on or in the ground. The standard 4-radial elevated system can work well but as the article shows it can also work not so well. The article is primarily intended to show why I suggest that 10-12 elevated radials should be used if possible. Download QEX Mar-Apr 2012 , 1MB, Download QEX May-Jun 2012, 2.4 MB.
