hamiltonOTA2.0 Thank you so much for your work optimizing these for the ch7 - 36 spectrum and sharing to the group! Planning to build your GH6n5 in the near future. I built a GH10n3 a few years back that is working extremely well. BUT it's showing some wear and tear, plus revealing to me where I could have built it a little better. I'm thinking the GH6n5 will be less of a "windsail" than the GH10n3. Thanks again!

As a n00b to VHF/UHF antenna building, how would I get the build parameters and models for any of these? Do I take the code and plug them into a specific NEC app, or...?
hamiltonOTA2.0 provided a link to the "model viewer". You should be able to hover your mouse over each segment of the antenna and it will show the dimension. What I did was print the front and side views of the "model view" and wrote the dimensions of each segment on the printed copy. As for the construction, Youtube has several videos of the construction process. I recommend watching several videos and develop your own method.

Hopefully it doesnt matter too much. It's only 3 inches shorter compared to the old 7-51 GH10n3 and basically the same amount of aluminum. So I'd guess the wind resistance would be very similar. Pics would be nice when you get it built :)
