Cell towers in Saint-Hilaire-du-Harcouet

1 church or religious building and 6 pylons carry the commune's antennas.

Masts stand at Beau Soleil, Zone D'Activités la Maison Neuve, Proche Route de l'Ange Suzanne, Miron, ZA de l Auberge Neuve and Les Pare Balles.

On 3.5 GHz, the fastest 5G band: Bouygues Telecom on 3 of its 4 masts, SFR on 3 of its 4 masts and Free Mobile on 2 of its 3 masts. No 3.5 GHz from Orange here, only 2100 MHz.

Systems from 1998 are still on the register. Free Mobile switched on the first 5G here in January 2021; Bouygues Telecom followed in September 2021, SFR followed in October 2021. 2016 was the busiest year, with 17 new systems, most of them 4G.

Approved additions not yet in service are pending on 3 existing masts, for example Free Mobile (4G 800 MHz) at Proche Route de l'Ange Suzanne, Free Mobile (4G and 5G, including 5G at 3.5 GHz) at Beau Soleil and Orange (2G, 4G and 5G, including 5G at 3.5 GHz) at place de la Motte. 6 Bouygues Telecom 5G transmitters are listed as technically operational — installed, but not yet declared commercially in service.

The highest support stands 56 m at place de la Motte (church or religious building). The median is 37 m, above the Manche median of 34 m.

Nearby, Fougeres (26 km to the south) has a higher 5G share (100%).

The widest declared gap between neighbouring supports is about 4.6 km, to the west of the centre.

Only one mast carries all four networks.

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