How much cost a TV station in the 40s/50s???

[Captain Video]

Anyone knows? How much you had to pay to RCA Victor sometime around 1948/1949 to buy a complete TV station, let's say one with three studio cameras, a film chain, a slide projector and a remote truck?

I am trying to do a research on this, because one author wrote that the first Brazilian TV station ( innaugurated in 1950 ) cost 5 million dollars, other said it cost only 300 thousand dollars. I want to find out who was right ( or more close to the truth ).
