Can it be that some parts of www.g0ksc.co.uk and www.innovantennas.com
are failing to load in your browser?
These are two different websites. g0ksc.com is mainly for homebrew
antenna constructors and includes a large number of designs with
detailed physical dimensions that anyone can model... and many have.
Anyone who is experienced in antenna modeling will already have an
extensive library of their own modelled plots and can make whatever
comparisons they may wish.
Innovantennas.com is the commercial website. The LFA page does include
comparison plots between the 9-element LFA for 6m and a similar antenna
from another company. The comparison antenna is not named (British law
about this form of advertising is tighter than you are accustomed to in
the USA) but once again, anyone with sufficient interest can easily
identify what "KHW" means.
Finally, you can look up the website of DUBUS magazine, which I already
mentioned, and find indexes that list at least 12 articles published by
G0KSC, along with many other articles about Yagi design. These are all
archived in the annual DUBUS-Technik publications which can be ordered
from your national DUBUS representative.
As others have said, the information is all there to be found.
