If you lived in a larger city, a smaller loop antenna could be used to pick up a strong local station. It was common to see these antenna wires stretched between buildings, across rooftops, and between trees. A long-wire antenna was just that, a single wire, 50 to 100 ft in length. Reception in many areas was only possible in the evening through the use of a “long wire” antenna. Since there were few radio stations it was necessary for many to pick up distant stations hundreds of miles away. This meant that a number of large storage batteries had to be maintained to power a tube radio. Vacuum tubes used at the time were not as energy efficient as today’s transistors and integrated circuits. Radio was quickly becoming popular, but because electricity was still not common or even available in many areas, most radios had to be battery powered.
