Only Orange broadcasts 5G at 3.5 GHz here, on 1 of its 2 masts. 50% of the town's masts carry 5G, fewer than across Eure-et-Loir towns with five or more masts (80%).

The commune owns 3 of the 6 masts, Cellnex owns 1.

2017 was the busiest year, with 9 new systems, most of them 4G. Local 5G started with Free Mobile in December 2020; SFR followed in May 2023, Bouygues Telecom followed in May 2023. The oldest transmitter still listed here goes back to 1997.

12 systems were switched on in the past 12 months. Approved additions not yet in service are pending on 2 existing masts, for example Bouygues Telecom (4G 700 MHz) at Chem des Trente Arpents, Free Mobile (4G 700 MHz) at Route de la Framboisiere and SFR (4G 700 MHz) at Chem des Trente Arpents. 1 Bouygues Telecom 5G transmitter is listed as technically operational — installed, but not yet declared commercially in service.

ANFR lists an 80 m radio relay tower at Chem des Trente Arpents as the tallest structure. The median is 36 m, above the Eure-et-Loir median of 31 m.

By mast count, Senonches is 9th of the 12 Eure-et-Loir towns that have five or more. With 6 masts for 3,045 residents, or 20 per 10,000, it has more masts per inhabitant than the median for those towns (7).

Supports leave a gap of about 3 km to the north-west of the centre.

Nearby, Tourouvre (28 km to the west) has less 5G (20%).

Of the 6 masts in the commune, 3 of the 6 masts host at least two operators.
