I am planning on building a UAV boat to go through waypoints using the APM 2.0. Which frequency should i get for using a ground station on the beach and having the boat go in the ocean, 433MHz or 915MHz. Does anyone know if I can do this or what kind of range since it will be over the water and not in the air?
Thanks, I guess I only have the option of 915MHz in the USA. With a 4 foot antenna do you think I would have a decent range?
