[amsat-bb] ARRL Antenna book, eggbeater antenna designs

[David Swanson]

Hi Sean!

I don't recall seeing any name calling here until your post, I genuinely
want to make sure the author of this thread who has sent numerous emails to
this list explaining how to operate gets the best tips in regards to their
planned build. I'm actually in the process of building the setup I
recommended and will plan on doing a demo for folks sometime here soon,
stay tuned!
