[Help] Telemetry Radio Suggestion


Can anybody suggest me a very long range 433 MHz Telemetry pair for Pixhawk 2.1 Cube?

Currently I’m having 3DR module of 500mW. But I need to communicate with my ArduPlane with maximum of 100 km without satellite communication.

I cannot use 900MHz because of rules and regulations in my country.

Thanks in Advance.
Good day.

Flying your aircraft beyond your ability to see-and-control it is very dangerous. In the event of something going wrong, you may hurt someone.

RC Control and telemetry on one radio using 433mhz. Designed for your application with Ardupilot.

can anybody suggest me a satellite based communication like iridium for a research project?
