Cell towers in Chatenay-Malabry

3 supports are declared underground, in a gallery or a tunnel. For questions about exposure, see the exposure guide.

Most of the town's 22 masts are buildings (15); 3 underground or tunnel sites, 1 bridge or viaduct and 1 church or religious building make up the rest of the mix.

Antennas are listed at 1 Allée des Aulnes, Avenue de la Division Leclerc, 354 avenue de la Division Leclerc, 10 Place Cyrano de Bergerac, Chemin de la Croix Blanche and 2 place Jean-Baptiste Corot.

Most antennas sit on rooftops (15 of 22), so heights stay modest; the tallest support is 40 m at 1 Allée des Aulnes.

Systems from 1996 are still on the register. Local 5G started with Bouygues Telecom in November 2020; Free Mobile followed in December 2020, SFR followed in December 2020. 2013 was the busiest year, with 45 new systems, most of them 4G.

Over the past 12 months ANFR recorded 17 new systems here. Approved additions not yet in service are pending on 6 existing masts, for example Bouygues Telecom (5G 3.5 GHz) at 4 allée des Marronniers, Free Mobile (4G 900 MHz) at 1 Allee des Fauvettes and Free Mobile (4G and 5G) at Bouquet de Verrières. 11 Bouygues Telecom 5G transmitters are listed as technically operational — installed, but not yet declared commercially in service.

On 3.5 GHz, the fastest 5G band: Free Mobile on 7 of its 9 masts, Orange on all 6 masts, SFR on 6 of its 10 masts and Bouygues Telecom on 4 of its 10 masts.

2.1 km to the north-east, neighbouring Sceaux has only 10 masts.

Colocation covers 11 supports.

At 6 km² with 35,825 residents, the commune is dense enough that most antennas sit on rooftops rather than pylons. It is part of the Métropole du Grand Paris intercommunal grouping.

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