BI1MMP Taking advantage of the hot weather and being able to go out in the evening, I thought about going to the park to talk to satellites. The antennas I previously purchased were quite heavy, and holding two antennas at once was tiring. I had always wanted to build a 2+3-element Yagi antenna. Finally, I consulted ZS6TVB's dimensions and model files to create: https://www.thingiverse.com/thing:2255079 I've been working on it intermittently for several weeks, and finally finished it. I hope to achieve more successful connections.
