SIZE:     L21* W16* H46cm
Function/Purpose:     In the 1960s, before satellite communication was developed, this triode was the powerful magnifying component of the transmitter set installed in the coastal radio station. Its main function is to magnify the lower power radio frequency signal into 3000 watts by class C modulation and then transmit it through the antenna. Being reflected by the ionosphere, the radio wave can travel all over the world including Asia, Europe, and America building communication between Taiwan and ships sailing every ocean.
