Cell towers in Dunkirk (Nord)

Most of the town's 46 masts are pylons (20); 2 churches or religious buildings and 2 water towers make up the rest of the mix.

Declared locations include Le Village de Mardyck, Bassin D'Évitage, rue Noort Gracht, rue Jean Moulin, Résidence Jean Bart and Rue Léon Blum.

46 systems were switched on in the past 12 months. ANFR has approved 2 new sites that are not live yet, plus additions on 13 existing masts. New: Free Mobile (4G and 5G) at Route de la Capitainerie Ouest and SFR (3G, 4G and 5G, including 5G at 3.5 GHz) at 800 Avenue de Rosendaël Jacques Collache. 29 Bouygues Telecom 5G transmitters are listed as technically operational — installed, but not yet declared commercially in service.

The commune owns 4 of the 46 masts, Totem owns 6.

2016 was the busiest year, with 152 new systems, most of them 4G. Free Mobile opened 5G here in December 2020; Orange followed in November 2021, SFR followed in November 2022. The oldest transmitter still listed here goes back to 1994.

ANFR lists a 97 m radio relay tower at Tour de Reuze as the tallest structure. The median height of measured supports is 33 m.

Of the 46 masts in the commune, 6 masts carry all four networks, and Orange is the only carrier on 12 masts.

3.5 GHz 5G is declared by Orange on 22 of its 25 masts, Bouygues Telecom on 14 of its 21 masts, Free Mobile on 14 of its 18 masts and SFR on 13 of its 24 masts.

Supports leave a gap of about 2 km to the west of the centre.

5.8 km to the west, neighbouring Grande-Synthe has only 15 masts.

By mast count, Dunkirk is 5th of the 94 Nord towns that have five or more. With 46 masts for 86,263 residents, or 5 per 10,000, it has fewer masts per inhabitant than the median for those towns (9).
