Cell towers in Mont-de-Marsan (Landes)

4 water towers and 7 pylons and 6 buildings carry the commune's antennas.

Masts stand at Beillet, Rue Rigoberta Menchu, Le Broca, 23 B boulevard des Pyrénées, Impasse la Hiroire and 138 rue Pierre Benoit.

2 masts belong to the commune itself and 4 to Hivory; 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 August 2021, Bouygues Telecom followed in September 2021. 2022 was the busiest year, with 44 new systems, most of them 5G.

Over the past 12 months ANFR recorded 25 new systems here. Approved additions not yet in service are pending on 3 existing masts, for example Bouygues Telecom (4G and 5G, including 5G at 3.5 GHz) at impasse du Carboué, Free Mobile (4G and 5G, including 5G at 3.5 GHz) at allée de St Angel and Free Mobile (4G and 5G, including 5G at 3.5 GHz) at Beillet. 15 Bouygues Telecom 5G transmitters are listed as technically operational — installed, but not yet declared commercially in service.

The highest support stands 54 m at allée de St Angel (water tower). The median is 33 m, slightly below the Landes median of 37 m.

2 masts carry all four networks.

Among the 28 Landes towns with at least five masts, Mont-de-Marsan ranks 2nd by mast count. With 17 masts for 31,592 residents, or 5 per 10,000, it has fewer masts per inhabitant than the median for those towns (12).

On 3.5 GHz, the fastest 5G band: Orange on all 9 masts, Bouygues Telecom on 6 of its 9 masts, Free Mobile on 6 of its 7 masts and SFR on 6 of its 9 masts.

Nearby, Saint-Pierre-du-Mont (2.1 km to the west) has only 6 masts.

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