Hey yall - I randomly found an RC/FPV brand that sells equipment that runs on 915mhz (US frequency for LoRa), here’s two antennas that I found on their website that should work with our devices:
Oh… wow… No clue why my brain did not click on that.
I run mostly crossfire on my UAVs, so I have a bunch of these antennas laying around.
Oh, and if you want real range, get their diamond antenna. I have been planning on getting one for my UAVs.
