They do not need mountain antennas because satellites are real & definitely not antennas & towers & weather balloons
Sounds to me like Satellites are a extra step that is not necessary
You can just use antennas to send signals to and receive signals from other antennas
@shortstories Satellites communicate by using radio waves to send signals to the antennas on the Earth. The antennas then capture those signals and process the information coming from those signals.
