Televisions First Mobile Unit...1937 On December 12, 1937, an RCA mobile system, consisting two 26 foot busses was delivered to NBC in New York City. One motor van provided two portable single-lens iconoscope cameras and their support equipment. The second van contained the 177 MHz transmitter with antenna which could relay a remote pickup to the Empire State Building from as far away as 25 miles. The units were used for about six months before being returned to RCAs Camden plant for modifications in the synchronizing equipment. Another modification was the installation of an coaxial feed out the transmitter truck. Seem that during testing, they hit on the idea of using the sunken cafe/skating rink area at Rockefeller Plaza as a on outdoor studio but could only get a signal out with the microwave dish, which didnt do well in the steel canyons of NYC. The trucks came back around August and on September 15, 1938, NBC conducted the first sidewalk interview with passers-by in Rockefeller Plaza. By the time the 1939 Worlds Fair came to town, NBC had a lot of experience with the units and used them heavily at the Fair. Enjoy and share!
