That looks like a solid portable setup.

My goal is actually pretty simple — to stay connected in case the internet or power goes out in my apartment building. The problem is, I'm in a wheelchair, so dealing with antennas myself is difficult, especially if they need to be mounted outside. And honestly, the whole LoRa thing is still pretty confusing to me. I'll just buy a few Lilygo or Heltec boards and figure things out little by little.
