Friends of the Irish Environment said it would negatively impact the biodiversity of the area.

It's planned for a site at Lisdaran, Cavan Town.

It's said this will allow vacant retail space to be better utilised.

Cavan County Council ruled that it wouldn't be granting permission because it would have an adverse impact on the local area.

Works will involve alterations and a change of use to an existing vacant two-storey building.

It ruled that the multi-operator monopole and antennas wouldn't impact on visual or residential amenities.

The Cavan Royal School in the townland of Lurganboy is a protected structure.

The works will "improve compliance and prolong the operational life of the plant".
