Masts stand at Les Dallets, Prat Long, St Vincent le Griffoulet, Les Ichers and Jeannes.

The declared supports are a 39 m pylon, at Les Dallets, for Bouygues Telecom, Free Mobile, Orange and SFR; a 36 m pylon, at Prat Long, for Free Mobile and Orange; a 34 m pylon, at St Vincent le Griffoulet, for Bouygues Telecom, Free Mobile, Orange and SFR; a 35 m pylon, at Les Ichers, for Bouygues Telecom and SFR; a 38 m pylon, at Jeannes, for Free Mobile.

ANFR has approved one new site that is not live yet, plus additions on 2 existing masts. New: Orange (4G and 5G) at La Pisse. 2 Bouygues Telecom 5G transmitters are listed as technically operational — installed, but not yet declared commercially in service.

The highest support stands 39 m at Les Dallets (pylon). The median is 36 m, above the Tarn median of 30 m.

Systems from 1998 are still on the register. Local 5G started with Free Mobile in December 2020; SFR followed in October 2022, Bouygues Telecom followed in November 2022. 2022 was the busiest year, with 15 new systems, most of them 4G.

On 3.5 GHz, the fastest 5G band: Bouygues Telecom on 1 of its 3 masts, Free Mobile on 1 of its 4 masts, Orange on 1 of its 3 masts and SFR on 1 of its 3 masts. 5G is on 60% of masts here, against 87% across Tarn towns with five or more masts.

2 masts carry all four networks.

Among the 16 Tarn towns with at least five masts, Lisle-sur-Tarn ranks 14th by mast count. With 5 masts for 4,939 residents, or 10 per 10,000, it has more masts per inhabitant than the median for those towns (8).

The widest declared gap between neighbouring supports is about 4.4 km, to the north of the centre. Most declared azimuths point outward, along a corridor or valley rather than at the centre.

13 km to the south-west, neighbouring Saint-Sulpice-la-Pointe has a higher 5G share (100%).

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