Per the FCC license archive, KEB525 power was 350W going back to earliest record on file (2001). Antenna height 170 ft (52.0m)
I always followed the "radio mechanic" (as they were called) into the building's basement, where the two Motorola transmitters were housed. That were the "A" and "B" transmitters. The radio mechanics were usually happy with an output of anything over 300 watts.
At the right side of the supervisor's position you might catch a glimpse in the video of a small Motorola "consolette" and microphone which was an emergency backup unit, and it was rarely used. Sometimes the Supervising Dispatcher would use it for a quick transmission if he (or she) did not want to walk over to the main radio console.
My recollection is that the transmitter and antenna for that "C" unit were located either at the Brooklyn Museum or the Brooklyn Public Library, both of which are in close proximity about 1/2 mile north of the Brooklyn Central Office and at a high ground elevation on Eastern Parkway just east of Grand Army Plaza. It was a lower powered unit, perhaps 100 watts or so.
The monopole antenna mast which you see in the video has since been replaced by a more conventional tower. When the mast was first erected (probably late 60's or so), in a compromise with the Brooklyn Botanical Gardens, the entire mast was painted sky blue in order not to distract from the aesthetic beauty for visitors to the botanic gardens. However, it was deemed a hazard to aviation after a few near-misses and was repainted with its red interval stripes to make it more visible.
Hopefully there are some FDNY historians here who can fill in some of the gaps regarding my recollection.
