The Langenberg transmission tower (also translated as "Sender Langenberg" or "Transmission Facility Langenberg") is a broadcasting station that transmits MW, FM and TV signals. It is located in Langenberg, Velbert, Germany and has had a very turbulent history since its inauguration. The transmitter first went into service in 1927 with 60 kilowatts (kW) of power and a T-aerial hanging on two 100-metre freestanding steel-frame towers insulated against ground.
