On the Earth, the signal fades due to the atmosphere. On the lunar rover, the antenna is small because there is no atmosphere, and on the Earth, the receiver is a giant round structure that measures meters or tens.
And the antenna design is also very important. For example, a TV antenna transmits in all directions, while a lunar rover transmits strictly upwards
Yes, that's what I meant "the receiver is a giant round structure that measures meters or tens"
In your quote I was talking about a TV antenna and a directional one.
