In legal practice, an antenna is the passive part of electronic communications apparatus that radiates and receives electromagnetic energy (radiofrequency signals), typically mounted on a mast, pole, tower or building to enable mobile, broadcast, Wi‑Fi or point‑to‑point links. The term is descriptive, but is defined for particular purposes in planning and telecoms regulation. In England and Wales, the Town and Country Planning (General Permitted Development) Order and guidance set limits on number, size and siting of antennas (including small cells and dishes) for permitted development or prior approval, and the Electronic Communications Code treats antennas as components of “electronic communications apparatus” relevant to wayleaves, access, upgrading and sharing. Broadly equivalent planning regimes apply in Scotland and Northern Ireland. In Ireland, the Planning and Development Regulations and related guidance govern siting, with radio use licensed by ComReg. In the UK, Ofcom licences spectrum use and oversees EMF compliance.
In practice, antennas feature in mast and rooftop leases, Code agreements, wayleaves and street works permissions, and raise issues of planning consent, design and siting, structural loading, interference management, EMF and health and safety, access, maintenance, upgrading, site sharing, and decommissioning or reinstatement.
