Hi, Michael.

It was a pleasure running into your booth at the Peoria (IL)
hamfest this past weekend.  I purchased one of your EF4010
antennas, as did my buddy, and with the beautiful day today
I thought I'd try it out.  I purchased the antenna with
portable operation in mind, so I set up my IC-7000 on a
table in the back yard and hoisted the antenna in a tree.
Within minutes I was on the air and made the following
contacts, all sideband, with 75 watts:

DL5ANT in Germany on 15 meters
CE4CT in Chile on 10 meters
KD8DZ in Ohio on 40 meters

I'm thrilled!  The antenna works as well or better than I
hoped.

73,

-Bill, KA9WKA
