Вот ответ самого производителя и начальника всех Byonics-ов Аллена Лорда
The actual range will generally be shorter than the maximum predicted range based purely on antenna height and power as the factors in determining the radio horizon. To calculate the actual range, you need to know the transmission path losses, antenna gain (on both sides) and the receiver sensitivity. My guess is that for trackers at an altitude of 300 meters, and a reasonably good receive antenna, you will be on the border of establishing a solid link. Packet collisions are another story. You have probably heard anecdotal stories of people hitting digipeaters at 1000 foot altitudes at ranges of several hundred miles, even with lower power transmitters. Air to ground is much more forgiving then radio waves carried over the water or ground. I would test the coverage before relying on it for an actual operation though!
