Controversial plans for a 5G mast near a South Oxhey school have been blocked for the second time amid hundreds of objections.

Vodafone had applied to erect a 17.5m antenna in Gosforth Lane under permitted development in July, just months after a previous application for a larger 20m aerial in the same spot was blocked by Three Rivers District Council.

But the prior approval application has been refused by district councillors on the grounds it would have “excessive height” and “appear as a visually incongruous, prominent, and obtrusive feature which would result in harm to the character and appearance of the street scene and wider area”.

The first application for a 20m tower in Ainsdale Road was withdrawn in April last year after a protest was held outside the gates and a petition was signed by 310 people.

When the plans returned this summer, they sparked a backlash among South Oxhey residents including Labour councillor Steve Cox who branded the mast “unsightly and incongruous”.

Carer John Eastwood, 64, spent days collecting 660 signatures on a petition against the mast, which was handed into the TRDC offices on August 27.

Many of the objections used a stock template which claimed the antenna would be “not in keeping with the local area and would not only be an eyesore but very intimidating to young children and older people as they look like something from a horror movie”.

It also warned that it would reduce local property values, making homes “harder to sell as a consequence”.

The objections also raised fears over alleged health risks from 5G radiation, although documents submitted with the application stated that research shows “no dangers” are linked to mobile communications radio signals when used “within guidelines”.

A Cornerstone spokesperson said it understood that mobile infrastructure can lead to concerns about proposed developments and that it "carefully considers" their location and design to integrate projects into the local area.

They added: "We are disappointed that our proposal was refused, and we are reviewing our options to provide digital connectivity infrastructure to the local community."
