Extending range on Holybro Sik Radios 915 mhz

PX4 Autopilot

Hello, I’m using the Holybro SIK 915 mhz telemetry radios for my fixed wing drone project. Wondering what’s the best antenna’s to use to extend the range to a couple km’s?

Would these antenna’s from TBS help extend the range?

Are you aware of the ArduPilot SiK docs?
https://ardupilot.org/copter/docs/common-3dr-radio-advanced-configuration-and-technical-information.html#power-levels

They are really good, and mention several points to increase range. The obvious one is to increase the power levels, depending on what is allowed in the area you fly in.

Thanks a lot, I hadn’t seen the ardupilot docs! Those are very helpful, thank you.
