Собственно вопрос в названии темы. Понимаю, что всё не однозначно, что на распространение радиоволн влияет много факторов и т.д. Прошу псетителей приводить факты из собственного опыта.
Накануне я испытал некое устройство, работающее на частоте 433 МГц. Получил дальность около 6 километров по земле в непрямой видимости (через перелески, поля, пригорки, кусты). Какую дальность можно ожидать по воздуху в прямой видимости антенн? А если передающую антенну сделать направленой, с шириной так 90°?
