Page 154, October 2002 QST:
"performs as predicted by YO and EZNEC within .25-.50 dB"
is patently unverifiable. I have no problem with the ad
included a chart based on computer modeling but they have
no way of proving that their actual physical HF antenna
is within .25-.50 dB of the computer models, especially
since they give free space gains and I am quite certain
the manufacturer does NOT have a free space antenna
Similarly, I am quite sure they have no way to confirm
that the actual conductor losses are .17 dB; rather the
model predicts losses of .17dB
Again, to summarize, the table is ok - but the
claimed accuracy puts them in the Gotham category
when it comes to accuracy in advertising.
