Need more radios to test range but with this antenna likely 1-3 miles.
But they’re fairly cheap. Mine was $90 but there are some you can find closer to $50

Id need to figure out a good 50 mile radius solution using meshtastic. I wonder how many devices I would need.
It would be nice for my local region to have this as a backup. I wouldn't mind paying for it if it helps us all in a disaster situation.
