WebJan 8, 2024 · That means ground antennas with an area of 2E+07 and 2E+05 m^2, or sizes of 4 km and 400 meters, respectively. These are huge! In other words, if you keep everything about the equipment the same, and try to tackle the large distance by simply scaling the Earth-based antenna size, it's not going to work.
