In 1887 Heinrich Hertz developed the first spark gap transmitter in the modern era.

A spark-gap transmitter is an obsolete type of radio transmitter which generates radio waves by means of an electric spark.[1][2] Spark-gap transmitters were the first type of radio transmitter, and were the main type used during the wireless telegraphy or "spark" era, the first three decades of radio, from 1887 to the end of World War I.[3][4] German physicist Heinrich Hertz built the first experimental spark-gap transmitters in 1887, with which he proved the existence of radio waves and studied their properties.
The Ark of the Covenant was a spark gap transmitter very similar to the early version spark gap transmitter by Hertz. But the Ark was thousands of years earlier.
On the left of the circuit diagram we have the person transmitting (the Priest). In the middle we have a spark gap transmitter with capacitor (the Ark).
Hertz used a battery but the Ark communication system did not use a battery. It used the piezoelectric energy generated by pressing a quartz gem.
In 1915, famed inventor and indisputable genius Nikola Tesla published an article entitled “The Wonder World to be Created by Electricity.” In it, he stated the following:
“Moses was undoubtedly a practical and skillful electrician far in advance of his time. The Bible describes precisely, and minutely, arrangements constituting a machine in which electricity was generated.”
