Place names on the register include 2 rue Henri Dunant, La Galathee, 19 rue Fauveau, 1-5 Ruelle de la Sourde, 40-46 rue Galliéni and 23 rue du Château.

ANFR has approved one new site that is not live yet, plus additions on one existing mast. New: Bouygues Telecom (3G, 4G and 5G) at 64 rue de Balzac. 8 Bouygues Telecom 5G transmitters are listed as technically operational — installed, but not yet declared commercially in service.

2021 was the busiest year, with 19 new systems, most of them 5G. Local 5G started with Bouygues Telecom in November 2020; Free Mobile followed in April 2021, SFR followed in September 2021. The oldest transmitter still listed here goes back to 1996.

7 of the 7 masts are rooftop-mounted. The tallest support is 39 m at 2 rue Henri Dunant (building). The median height of measured supports is 25 m.

3.5 GHz 5G is declared by Bouygues Telecom on all 4 masts, Free Mobile on all 4 masts, Orange on all 2 masts and SFR on all 2 masts.

Montmorency lies 1.7 km to the north-east and has 11 masts, more than here.

Of the 7 masts in the commune, 3 of the 7 masts host at least two operators.

By mast count, Deuil-la-Barre is 33rd of the 43 Val-d'Oise towns that have five or more. With 7 masts for 23,099 residents, or 3 per 10,000, it has fewer masts per inhabitant than the median for those towns (6).

At 4 km² with 23,099 residents, the commune is dense enough that most antennas sit on rooftops rather than pylons.
