Cell towers in Saint-Jean-de-Monts (Vendée)

1 water tower and 15 pylons and 1 building carry the commune's antennas.

Masts stand at Le Petit Sochard, ZAC du Clousis, Les Vignes, avenue des Demoiselles, La Vacherie and 14 Rue des Artisans.

Over the past 12 months ANFR recorded 13 new systems here. ANFR has approved one new site that is not live yet, plus additions on 4 existing masts. New: Free Mobile (4G and 5G, including 5G at 3.5 GHz) at 7 Chemin de la Rouillere. 15 Bouygues Telecom 5G transmitters are listed as technically operational — installed, but not yet declared commercially in service.

The tallest structure is a 55 m water tower at boulevard Mal Leclerc. The median is 25 m, slightly below the Vendée median of 32 m.

Systems from 1997 are still on the register. Free Mobile opened 5G here in December 2020; Orange followed in July 2021, Bouygues Telecom followed in July 2022. 2022 was the busiest year, with 61 new systems, most of them 4G.

Among the 29 Vendée towns with at least five masts, Saint-Jean-de-Monts ranks 3rd by mast count. With 17 masts for 8,868 residents, or 19 per 10,000, it has more masts per inhabitant than the median for those towns (11).

On 3.5 GHz, the fastest 5G band: Bouygues Telecom on 7 of its 8 masts, Free Mobile on all 6 masts, SFR on 6 of its 7 masts and Orange on 5 of its 6 masts.

6.8 km to the north-west, neighbouring Notre-Dame-de-Monts has only 5 masts.

Only one mast carries all four networks; 5 supports carry only Free Mobile.

Most declared azimuths point outward, along a corridor or valley rather than at the centre.

8,868 residents over 62 km²: supports are mostly pylons, not rooftops. It is part of the CC Océan Marais de Monts intercommunal grouping.

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