- Telefunken Audio Frequency Amplifier, circa 1920 - This radio equipment was used at the German-built Tuckerton Wireless Station in New Jersey. A powerful 820-foot antenna communicated with an identical station in Germany. National security concerns during WWI led to the seizure of Tuckerton by the U.S. government in 1917. It is cited to be the origin of information leaks leading to the RMS <em>Lusitania</em> disaster through U-boat attack.

- Telefunken Induction Coil, 1912-1914 - An induction coil creates a high-voltage, pulsating current which arcs across a "spark gap." The spark creates electromagnetic waves, which can then be detected by a radio receiver. Induction coils were essential to the first decades of wireless and radio. Used from the late 1880s until the 1920s, spark gap powered radios were replaced as vacuum tube transmitters became available.
