Actually, you need to study as much of the data on N6LF's web site as you 
can -- www.antennasbyn6lf.com -- there is a lot of material on measurement 
techniques and other essential topics. In situ measurement at HF is a huge 
undertaking! Thanks, Rudy!

As noted by others, there are some portions of the discussion of elevated 
radials that could be expanded upon. I'd include N6LF's reference to the 
interesting, but since disproven, work by K5IU on unequal radial currents. 
However, in this case N6LF did arrive at the correct conclusion that small 
numbers of elevated radials need to be resonant.
