  1.  jeff deathrage  hi! Ham Radio operator here. We frequently bounce radio signals off the atmosphere to get long distance communications, and other times go through the atmosphere to bounce off the moon, or to reach satellites. (hams have put up many small satellites over the years, and there is also a Ham station on the ISS) The difference between the signals that go through the atmosphere, and the ones that bounce off is wavelength and angle. You know how if you throw a rock down into a lake, it splashes and sinks, but if you throw it at a low angle it bounces and skips? Radio waves work like that. And just like a large flat rock skips better, longer wavelengths (low frequency) gets better skip on the atmosphere. When you see the ham radio guys with LOOONG wire antennas, or wide yagi elements, they are probably using the low frequencies to get ionospheric skip, which can reach around the globe with just a few watts under perfect conditions. However, if you aim that antenna so that the same signal goes straight up, it blasts right through the ionosphere. And what do you mean they had no battery on the moon? They had batteries and fuel cells for electricity, which is how they ran the camera and transmitter.
