The reality where I live (North of England) is the opposite: cash-strapped (and often greasy-palmed) councils will approve masts willy-nilly, to the annoyance of locals who find out only after they're erected. Very occasionally this generates any actual organised blowback.
I'm curious, what are the actual objections to mobile masts being erected? They don't make a noise, they're not (despite the conspiracy theorists) in any way dangerous. All I can think of is that people don't like the way they look, but I don't really see them as being any uglier than a lamppost or street sign.
Mainly aesthetics, the new 5G masts are much larger and need to be sited in densely populated areas where there is already a significant amount of unwelcome street furniture.
Conspiracy theories regarding harmful radiation can also be a factor.
