A local councillor has raised his concerns after a plan was put forward to install a 5G mast outside a church in Sheffield.
George Lindars-Hammond, a Hillsborough councillor is among 17 people prompting the council to reject the plan.
Three, a mobile network operator has submitted a plan to Sheffield City Council to build the mast outside Wadsley Church on Worall Road.
In an interview with the BBC Mr Lindars-Hammond said: "I want to make sure we protect our beautiful church from this ugly and unnecessary mast."
"I have objected in the strongest terms to this application,"
Network provider Three said the plan to build the mast was to provide successful telecommunications "while minimising visual impact."
Tom Gallivan, from Three, told the BBC: "The use of the public highway to accommodate a new telecommunications installation complies with both central government and local planning policy guidance, where the underlying aim is to provide an efficient and competitive telecommunication system for the benefit of the community, while minimising visual impact.
