Cell towers in Concarneau (Finistère)

Masts stand at La Croix Neuve, 11 rue Jacques-Noël Sane, Keroulin, Kerveil, 33 boulevard de Bougainville and Kerandon.

ANFR has approved one new site that is not live yet, plus additions on 2 existing masts. New: Bouygues Telecom (3G, 4G and 5G, including 5G at 3.5 GHz) at Valcor. 7 Bouygues Telecom 5G transmitters are listed as technically operational — installed, but not yet declared commercially in service.

The tallest structure is a 65 m pylon at Kergrac'H. The median height of measured supports is 30 m.

Systems from 1998 are still on the register. Free Mobile opened 5G here in December 2020; Bouygues Telecom followed in September 2021, SFR followed in September 2021. 2019 was the busiest year, with 26 new systems, most of them 4G.

On 3.5 GHz, the fastest 5G band: Orange on 5 of its 7 masts, Bouygues Telecom on 2 of its 5 masts, SFR on 2 of its 5 masts and Free Mobile on 1 of its 5 masts.

Tregunc lies 5.4 km to the south-east and has only 7 masts.

The widest declared gap between neighbouring supports is about 2.7 km, to the north of the centre.

Only one mast carries all four networks; 3 supports carry only Orange.

Among the 38 Finistère towns with at least five masts, Concarneau ranks 5th by mast count. With 11 masts for 20,845 residents, or 5 per 10,000, it has fewer masts per inhabitant than the median for those towns (10).

Most of the town's 11 masts are pylons (6).

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