The decision has dismayed Coun Amanda Carter (Con, Calverley and Farsley) who wants planning laws to be reviewed.
Leeds West plans panel gave T-Mobile permission to site a mast, disguised as a flagpole, on St John's Parish Church in Farsley.
Some 275 residents, two schools and ward councillors all objected.
"It is frustrating that we were unable to stop this mast from being placed in a densely-populated area," said Coun Carter.

"The councillors are not allowed to take health issues into account and we could not stop the mast on the grounds that the church is a listed building in a conservation area.
"I want to see the Government look again at planning laws for mobile phone companies. It's outrageous that a substantial amount of public opinion can be overlooked like this. In this case there are plenty of other mast sites away from schools and residents where this could have been erected – such as the ring road."
