Great to see the detailed tutorial, which reminded me of this forum dedicated to Antenna R&D (mostly for TV and FM Radio but also other types) that has a wealth of info on DIY techniques, physical structures, fabrication, theory, testing, etc.
Great to hear! And if memory serves correct, long time no see (Belgium like 11 years ago? haha) :) the Greek Mozilla squad was tons of fun to hang out with, super interesting discussions that day- project I mentioned briefly back then got awarded by NASA one year later, wish what I did was half as impactful than what you guys got going on at Libre Space though! Hope all is well
