I’ve never worked the ISS or a satellite but it’s on my list. Building a good yagi seems daunting. Also duplexing confuses me a bit when it comes to using my HTs
I've had some success using a basic tape measure yagi and a Baofeng. https://www.jpole-antenna.com/2017/02/07/build-it-2-meter-tape-measure-yagi-beam-antenna/
