Cell towers in Dax (Landes)

1 camouflaged "tree" pylon and 9 buildings, 4 pylons and 1 water tower carry the commune's antennas.

Declared locations include Constantine, Rue Jean Jacques Rousseau, Berdot, rue de Tercis, Coustaou and rue J.jacques Rousseau.

The highest support stands 63 m at Coustaou (water tower). The median is 31 m, slightly below the Landes median of 37 m.

2021 was the busiest year, with 24 new systems, most of them 5G. Local 5G started with Free Mobile in December 2020; SFR followed in August 2021, Bouygues Telecom followed in September 2021. The oldest transmitter still listed here goes back to 1999.

26 systems were switched on in the past 12 months. 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 8 Esplanade Charles de Gaulle, Bouygues Telecom (4G and 5G, including 5G at 3.5 GHz) at 2 Rue Buffon and Orange (4G and 5G) at rue de Tercis. 7 Bouygues Telecom 5G transmitters are listed as technically operational — installed, but not yet declared commercially in service.

Of the 16 masts in the commune, only one mast carries all four networks, and Orange is the only carrier on 7 masts.

By mast count, Dax is 3rd of the 28 Landes towns that have five or more. With 16 masts for 22,109 residents, or 7 per 10,000, it has fewer masts per inhabitant than the median for those towns (12).

3.5 GHz 5G is declared by Free Mobile on all 7 masts, Orange on 7 of its 9 masts, SFR on all 5 masts and Bouygues Telecom on 3 of its 4 masts.

13 km to the north-east, neighbouring Pontonx-sur-l'Adour has only 5 masts.
