There were tests done in NYC by a major network to verify this. They
estimated that it would take 4-5 transmission sites.
That being said, a city like New York would benefit from many
localized low-power repeaters to serve RF challenged areas, like
inside Grand Central station.
Every study I have seen indicates that it will take only a handful of
synchronized transmitters at a height of 300-500 feet, with power
levels no higher than about 10-50 KW ERP, to provide reliable
reception in cities like New York.
