I have been using a couple of 915MHz “SiK” telemetry radios for my autonomous drone project. The antennas on these are super fragile. The one on the drone broke at the joint on a hard landing the other day. I managed to put it together using a steel wire clip, as seen below, but I am basically just counting the days until it will break again.
Does anyone know what other 915MHz antennas can be used for these radios that are a bit more durable?
- Can ELRS “Moxon” antennas be used (although those are directional)?
- Can Crossfire “Immortal” T antennas be used?
- Are there any other designs with a flexible base for 915MHz, like the omni 5.8GHz antennas we use for FPV video?
…and “fixed” (for now):
