The first Mobile phone Invented was used as a Prop on Star trek the Voyage Home.

It consisted of a bunch of Radio Valves mounted on piece of wood linked in parallel cross linked through a set of amplifier valves and flip-flop valves (transistors), the amplifier valves were on a separate piece of wood and the flip-flop valves were also on a separate piece of wood. The Flip-flop valves worked to modulate the signal, and the amplifier valves worked to change the amplitude of the signal the radio valves determend the frequency.

The three rows of valves were connected to a Cathode Ray Tube which was powered by Car Batteries linked in series run though an inverter. (converts AC to DC and the other way round too depending on how it is wired)

It holds the record for being the biggest Mobile Phone ever. The following year voice capability was added to it. If it was to go on the market or up for auction it would sell for over $500 million.
