Topband: Skirted vertical antennas for MF broadcast

[Hamilton Hicks,Jr]

 Some years ago, I recall an AM station in Washington, DC, having their tower on the roof of a three story building. It was either a unipole or had skirted radials. I want to say that it may have been1340 khz.

 The first time I saw one it was called the Folded Umbrella and was
popularized by the late WB5IIR, John Haerle.  He wrote an article for HR in
May of 1979.  He also described it in his book, "The Easy Way."  I've been
using my own version of the basic design on 160 for several years.
