Skydriver dubulg'a kamerasi uchun simsiz video audio uzatuvchi va qabul qiluvchi

Hi, I am looking for a system capable of transmitting video and audio from an action cam (HD at least) installed on a skydiver helmet (uzatuvchi) to a tv/laptop in the ground (5km max). Do you have something built in that can work for that? minnatdorchilik
