Spark-gap transmitter

（重定向自Spark transmitter）

A typical spark transmitter circuit.
Legend: capacitor - C1 and C2; resistor - R; inductor - L.

A spark-gap transmitter is a device that generates radio frequency electromagnetic waves using a spark gap.

Spark gap transmitters were the first devices to demonstrate practical radio transmission, and were the standard technology for the first three decades of radio (1887–1916). Later, more efficient transmitters were developed based on rotary machines like the high-speed Alexanderson alternators and the static Poulsen Arc generators.
