I just finishing lofting the W3EDP antenna into the sky. I guess it is guaranteed to work, because:
A) I decided to do this on the day that a major DX contest if underway, and
B) I waited for the coldest day of Thanksgiving weekend to do it! Temperature is only 42F (5C) and the very gust winds are causing wind chill factor, making it feel like the low 30's (closer to 0C). My fingers were freezing while tying knots in the antenna rope and untying knots (tangles) in the antenna wire.
Just to make sure that I did in fact, not waste a good portion of the afternoon, I made two quick contacts. One was a contest QSO with C6AQM on 20 Meters and the other was a short rag chew with Bob N1MFW on 30 Meters.
So the antenna works! How well will remain to be determined as I use it more and more. So currently the antenna set up is the Butternut HF9V as Antenna 1 and the Antenna 2 outlet of the K3 goes to my antenna switch, where I can pick either the W3EDP or the 88' EDZ.
