I have been using YO off and on for quite a few years and am very happy
with the product. I have noticed, however, that the dimensions produced in
the program for the hairpin match have not been accurate with the design.
N2NC proved to me a couple of years back that there is in fact a problem in
He took a known quanity, a HyGain 204BA and modelled it in YO with the beta
match dimensions. It did not produce accurate results.
He then took the same file and exported it to AO. He then manually
inserted the EXACT same dimensions for the hairpin in to AO. BINGO.
Again, this was a few years ago. Maybe Brian has changed the code since
then. I havn't asked him.
I wonder if anyone else has seen these types of results while modelling
hairpin matches in YO? If so, how much were you off from the computer model?
