I have just completed my v3 rotator, and I’m now about to make my antenna. As my goal is first to connect to the ISS, I wanted to make a 145mhz Yagi Antenna. I have found the v3 on gitlab https://gitlab.com/librespacefoundation/satnogs/satnogs-antennas/tree/master/Yagi/Yagi-VHF-v3
All is good about the dimensions, but my question is about the material. Should it be copper, brass, alu? Does it make a difference? Thanks a lot!
