Cell towers in Tregunc (Finistère)

Most of the town's 7 masts are pylons (5); 2 water towers make up the rest of the mix.

Declared locations include Trévignon, Kerstrat, La Boissière, Kerouel, Kergleuhan and Stang Quelfen.

The highest support stands 42 m at La Boissière (pylon). The median height of measured supports is 32 m.

2015 was the busiest year, with 15 new systems, most of them 4G. Free Mobile switched on the first 5G here in December 2020; Bouygues Telecom followed in January 2022, SFR followed in February 2022. The oldest transmitter still listed here goes back to 1998.

Approved additions not yet in service are pending on 4 existing masts, for example Bouygues Telecom (4G and 5G, including 5G at 3.5 GHz) at La Boissière, Bouygues Telecom (5G, including 5G at 3.5 GHz) at Stang Quelfen and Orange (5G, including 5G at 3.5 GHz) at Kergleuhan. 3 Bouygues Telecom 5G transmitters are listed as technically operational — installed, but not yet declared commercially in service.

3.5 GHz 5G is declared by Orange on 3 of its 4 masts, Free Mobile on 2 of its 4 masts, Bouygues Telecom on 1 of its 3 masts and SFR on 1 of its 3 masts. 71% of the town's masts carry 5G, fewer than across Finistère towns with five or more masts (85%).

Nearby, Concarneau (5.4 km to the north-west) has 11 masts, more than here.

Supports leave a gap of about 2.5 km to the north-east of the centre.

Of the 7 masts in the commune, 5 of the 7 masts host at least two operators.
