Well, my Ham Radio experience tells me that radio is VERY directional, especially at high frequencies! Ever hear of EME bouncing? Basically, ya take a very short wavelength (in the low digit Gigaherz range) Yagi antenna, aim it at the moon and it maybe bounces back somewhere here on earth. I've been in the presence of conversations with folks from Agentina... all via radio waves bouncing off the moon.
