If you are on a planet and seeking to send out a signal for rescue from someone on another planet, you would not require higher ground as we need to when sending FM or AM radio signals as the signal would be sent out straight up into and through the atmosphere and into space. It would not need to clear hills or mountains or other obstacles.

That is a good point, thank you
