Looking for an Easy‑to‑Use Satellite Antenna for This Summer Hey everyone — I’m hoping to get on the satellites this summer, but I’m running into a few limitations and could use some advice or maybe even a used antenna if someone has one they’re not using. I can’t afford the Arrow handheld satellite antennas, and I no longer have the dexterity to build something like a Moxon or Arrow‑style yagi myself. I operate from a wheelchair, so whatever I use needs to be easy to hold or mount on a tripod. If anyone has: - A lightweight handheld yagi - A tripod‑friendly satellite antenna - A simple homebrew design you have built Let me know!
