Cell towers in Trebeurden (Côtes-d'Armor)

Most of the town's 7 masts are pylons (5); 1 water tower make up the rest of the mix.

Antennas are listed at Parc Lan Bras Poul Berthosrenon Alain, Lann Ar Hleïz, Chem de Milin Ar Lan, 2 rue des Hortensias, Lannec An Dimezel and Coz Forn Fall.

ANFR lists a 39 m building at 2 rue des Hortensias as the tallest structure. The median is 28 m, slightly below the Côtes-d'Armor median of 34 m.

Systems from 1997 are still on the register. Free Mobile switched on the first 5G here in December 2020; SFR followed in October 2021, Bouygues Telecom followed in October 2021. 2016 was the busiest year, with 13 new systems, most of them 4G.

Over the past 12 months ANFR recorded 14 new systems here. Approved additions not yet in service are pending on 2 existing masts, for example Free Mobile (5G 3.5 GHz) at Coz Forn Fall and Orange (4G 700 MHz) at 2 rue des Hortensias. 5 Bouygues Telecom 5G transmitters are listed as technically operational — installed, but not yet declared commercially in service.

2 masts carry all four networks; 3 supports carry only Orange.

3 masts belong to Totem and 1 to ATC France.

On 3.5 GHz, the fastest 5G band: Orange on 3 of its 5 masts, Bouygues Telecom on 2 of its 3 masts, Free Mobile on 2 of its 4 masts and SFR on 2 of its 3 masts.

The widest declared gap between neighbouring supports is about 1.8 km, to the south-east of the centre.

Nearby, Plouigneau (25 km to the south-west) has 13 masts, more than here.

Figures above cover installations declared to ANFR as in service or technically operational, as of October 2026; approved projects are not counted.
