I am looking for an antenna system (both transmitter and receiver) for a hight altitude balloon project. The payload will be equipped with environmental sensors as well as GoPro Camera. We like to receive the real-time data from sensors and camera (pictures/video) on ground (stationary base station). The balloon is expected to reach heights up to 100,000 ft.
Please advise a circularly polarized (RHCP) antenna system that will work with our project.
