"The smallest station I have contacted was a Canadian station on Vancouver Island. He had 150 watts at his transmitter, and about 90 watts at his antenna, which was only 14 feet long. However, he was located on the coast and the moon was close to his horizon. The signal becomes much stronger if you are pointed nearly horizontally, particularly over salt water, due to ground reflections. Unfortunately I can never point horizontally because my horizons are full of trees. Signals do not penetrate dense vegetation very well."
