Cell towers in Pontorson (Manche)

Declared supports include 1 water tower, with pylons making up most of the remainder.

Masts stand at Les Echaussees les Pas, La Rive Ardevon, rue de la Plaine, La Planche au Maître Ardevon, 7 Route du Desert les Pas and Loumel.

ANFR lists a 40 m pylon at rue de la Plaine as the tallest structure. The median height of measured supports is 33 m.

2 masts belong to the commune itself and 2 to TDF; the rest sit mainly on private buildings.

Systems from 1996 are still on the register. Free Mobile opened 5G here in December 2020; SFR followed in January 2022, Bouygues Telecom followed in January 2022. 2021 was the busiest year, with 16 new systems, most of them 4G.

Over the past 12 months ANFR recorded 10 new systems here. Approved additions not yet in service are pending on 4 existing masts, for example Orange (4G and 5G, including 5G at 3.5 GHz) at rue de la Plaine, Orange (5G, including 5G at 3.5 GHz) at La Justice Boucey and Orange (5G 700 MHz) at 7 Route du Desert les Pas. 7 Bouygues Telecom 5G transmitters are listed as technically operational — installed, but not yet declared commercially in service.

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

The widest declared gap between neighbouring supports is about 6 km, to the south-east of the centre.

14 km to the west, neighbouring Baguer-Pican has a higher 5G share (100%).

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.
