[Mesh] Satellite dish antennas

[Miguel Vargas]

Yea, I am going to need help getting them over there. They need to be
unmounted from their current locations and it will be a lot of stuff to
carry. I'm only about a mile from sudoroom and I'm generally available,

The usb stick seems like a good simple solution. We could start looking at
other designs if we end up needing more performance.
