In one of my earlier posts I had some information on the relationship between vertical height and optimum radial lengths. That information was buried in a larger document discussing several other items an was not that easy to find, so I've pulled that discussion out as a separate download: Download Vertical height versus radial system . What it shows is that there is a case to be made that, for a given total length of wire, more numerous shorter radials can be helpful on short verticals. At least up to point.
