What is the approximate maximum separation measured along the surface of the Earth between two stations communicating by EME?
Pick an answer to check it.
Answer: D. 12,000 miles, if the moon is “visible” by both stations
For EME, both stations just need the moon above their horizons at the same time. That allows contacts up to about 12,000 miles apart, nearly half way around the Earth.
Tip: Both see the moon: up to 12,000 miles.
