Because it only needs one.
Indeed, and of course Winter Hill is a legacy from 1956, when the ITA were looking to cover the north of England on Band III VHF. The BBC had managed the same for Band I ( 405 line BBC tv) and Band II (FM radio) by using a single site, Holme Moss, on top of the Pennines. The ITA looked at a site there, or nearby there too but at Band III the signal would not have reached the west and east coasts of Lancs and Yorks, so they opted for Winter Hill, used for 'Lancs', and Emley Moor for 'Yorks'
Granada (and ABC weekends) 1956 to 68 of course used both transmitters.
In the 60s, with the BBC and ITA jointly establishing sites for UHF/625 coverage, Holme Moss
was deemed totally unsuitable, so Winter Hill and Emley were selected for UHF, and both started transmitting BBC 2.
In 1968 the ITA split the north franchise between Lancs and Yorks, with Yorkshire TV allocated Emley, and Granada keeping Winter Hill, but for 7 days a week. At that point too, the BBC added a Band III transmission
of BBC 1 North from Manchester in addition to the Band I BBC 1 service from Holme Moss, but opened a new region from Leeds (to mirror ITV's arrangement) Holme Moss carried BBC Leeds, as did Emley when BBC 1 UHF started from there in Nov 69. Winter Hill carried BBC 1 North West and Granada UHF from Nov 69
What's the reason for the Granada area only having one transmittor?
