Masts stand at A11 Chartres-Est, Rue Jules Courtois, ZI Cassin, 2 Rue Blaise Pascal, rue Vincent Chevard and La Madeleine.
Most antennas sit on rooftops (15 of 20), so heights stay modest; the tallest support is 72 m at Rue Jules Courtois.
Over the past 12 months ANFR recorded 15 new systems here. ANFR has approved 2 new sites that are not live yet, plus additions on 9 existing masts. New: Bouygues Telecom (3G, 4G and 5G, including 5G at 3.5 GHz) at 103 Rue de Sours, Free Mobile (4G and 5G, including 5G at 3.5 GHz) at 103 Rue de Sours and SFR (3G, 4G and 5G, including 5G at 3.5 GHz) at 103 Rue de Sours. 7 Bouygues Telecom 5G transmitters are listed as technically operational — installed, but not yet declared commercially in service.
2 masts belong to the commune itself and 1 to TDF; the rest sit mainly on private buildings.
Systems from 1996 are still on the register. Free Mobile switched on the first 5G here in December 2020; SFR followed in August 2021, Bouygues Telecom followed in August 2021. 2021 was the busiest year, with 45 new systems, most of them 5G.
Only one mast carries all four networks; 8 supports carry only Orange.
Among the 12 Eure-et-Loir towns with at least five masts, Chartres ranks 1st by mast count. With 20 masts for 38,324 residents, or 5 per 10,000, it has fewer masts per inhabitant than the median for those towns (7).
On 3.5 GHz, the fastest 5G band: Orange on 7 of its 12 masts, Free Mobile on 6 of its 7 masts, Bouygues Telecom on 2 of its 7 masts and SFR on 2 of its 8 masts.
Luce lies 2.2 km to the south-west and has only 11 masts.
Most declared azimuths point outward, along a corridor or valley rather than at the centre.
At 17 km² with 38,324 residents, the commune is dense enough that most antennas sit on rooftops rather than pylons. It is part of the CA Chartres Métropole intercommunal grouping.
Supports split between 15 buildings and 5 pylons.
Figures above cover installations declared to ANFR as in service or technically operational, as of October 2026; approved projects are not counted.
