Spark Gap Transmitter, 1910-1925
01
Artifact Overview
Spark gap transmitters were the first means of practical radio transmission for the first thirty years of radio development. By the end of WWI, vacuum tube technology advanced sufficiently, replacing the spark gap. Even though the vacuum tube ensured more efficient and reliable transmissions, commercial use of spark gap transmitters continued up until WWII as back-up transmitters.
