Saw this antenna on DigiKey and wondered if it would work with the 433MHz telemetry radios. It would look good on a plane.


I’m sure it would work if -.9dBi gain is OK for your use case.

I just noticed that, but thanks. The normal antennas are 2 or 3 dBi, right?

Yes, around there. There are some 5dBi claimed units. But maybe it can work for you depending on your range requirement. I use ESP8266 WiFi radios an several craft. Not so much for telemetry, although they will do that short range, but for general configuration and calibration purposes.
