The frequency of the transmitter and the antenna has more effect on the range than the wattage. A 5 watt CB radio with a good antenna can reach thousands of miles using reflection off the Heaviside layer. Short wave broadcast stations use this technique to reach 1/2 way around the world. At frequencies above 100 mHz, transmission is mostly line of sight. A transmitter that might reach the moon would not penitrate the other side of a 10 mile hill.
