Felix, first of all, there needs to be a comparison with other
antennas over a number of different days with different conditions.
Secondly, I can't believe 59 reports from DX stations (I know, this
puts you into a handicap situation.) The problem is that many DX
stations will report 59 and ask you to repeat your call or name a
hundred times. The test really needs to be handled in an antenna
shootout of sorts. I have a 20 meter hamstick on my car and I often
get 59 reports from dx as well as CONUS stations. When band
conditions are well, I can get a 59 signal from a qrp rig. The real
test of the antenna will be with comparing the reception and reports
with the weakest stations. It takes a tremendous power change to
change a strong signal's report.



Additionally, you claim to be the creator of this antenna. This is
also a problem since you are trying to profit from it's plans. You
don't have calibrated or calculated gain/loss, bandwidth or radiation
patterns. What's to say your antenna is any better than the grasswire
antenna if you haven't compared them?
