now this is a thought experiment. let's say i have a transmitter 1 meter above the ground broadcasting at 200 megahertz. using the equation horizon in kilometers equals square root of transmitter height in meters times 3.569. i calculate the horizon is 3.569 kilometers away. let's say there is a helicopter 7.138 kilometers away hovering 1 mile above the ground. would the radio signal reach the helicopter? if so, the helicopter has a radio receiver sensitive enough to detect the radio signal. just trying to understand the physics of radio.
