Opposition to the siting of new police communication masts in Cornwall is to be addressed at a public meeting.
There are plans to extend the Bossiney mast by four metres
Devon and Cornwall Police is holding a discussion in St Ives on Wednesday night in an attempt to answer objections to the positioning of the Tetra mast system.
Protests have been held across the county, including Bossiney in north Cornwall, because residents fear the masts emit harmful radiation.
Masts are to be installed to improve radio links for the emergency services as part of a £3bn network funded by the government.
The officer in charge of the scheme in Cornwall, Chief Inspector Dennis Calver, said the meeting would help residents understand the changing needs of the police.
"I think it is important we try to help the public understand our desperate need, as a police service, for a new communications system so we can do the job better in the communities that we serve.
"We don't like being in conflict with the public and sometimes there is misinformation and misunderstanding," he said.
