You also make yourself a bright shining beacon to anybody looking for a resistance network because Lora operates on very specific frequencies. It would be easy to spot you with an RF scanner.
Any licensed wireless networking gear is going to operate in very specific frequencies. The government requires it! If we were going for "the best" gear for avoiding detection you would have frequency hopping with jumps far enough apart that a listener has a harder time pinpointing a transmitter. Making repeaters roving makes it even harder for your adversary.
If the place you are at is at that point in the conflict, RF scanners are the least of your worries.
Semtech LoRa Modems are wide frequency range modems. Latest generation also supports (non-LoRa) frequency hopping.
The signals are difficult to spot once you are in some distance to the transmitter.
Obviously, put that relay node on a hill, on some structure where you don't live. Or maybe on the roof of your tall apartment building, among all the satellite dishes and their associated boxes. Pretend to be one of those.
If it's a self-contained, solar-powered node, it needs not be next to you, or to anyone. It should be safe and secure, to be of use during a natural disaster, or an outburst of violence.
