As a long-time user of the "folded umbrella" on 160, I am very grateful
to the late John Haerle, WB5IIR, who brought the antenna to my attention
in his article in Ham Radio Magazine and in his little book called "The
Easy Way." The thing works and is relatively easy to put up and get
working. Haerle's erroneous claim regarding decreased ground losses has
resulted in most of the attention given to the antenna to be of a
critical nature. That's too bad, because if you have a 50-75 ft tower
and want to get on 160 with a low angle radiator, this antenna would get
you there with modest effort and very low cost!
