Most of the town's 5 masts are pylons (3); 2 churches or religious buildings make up the rest of the mix.

Masts stand at Complexe Sportif de la Viauderie - Rue de la Viauderie, La Lande Malbrais, La Princetière and place de l'Eglise.

The declared supports are a 26 m pylon, at Complexe Sportif de la Viauderie - Rue de la Viauderie, for Free Mobile; a 36 m pylon, at La Lande Malbrais, for Free Mobile and Orange; a 44 m pylon, at La Princetière, for Free Mobile and Orange; a 35 m church or religious building, at place de l'Eglise, for Bouygues Telecom, Orange and SFR.

ANFR lists a 44 m pylon at La Princetière as the tallest structure. The median height of measured supports is 35 m.

Systems from 1998 are still on the register. Local 5G started with Free Mobile in December 2020; Bouygues Telecom followed in April 2022, SFR followed in October 2022. 2018 was the busiest year, with 11 new systems, most of them 4G.

Approved additions not yet in service are pending on 2 existing masts, for example Orange (5G, including 5G at 3.5 GHz) at place de l'Eglise and Orange (4G and 5G, including 5G at 3.5 GHz) at Rond Point de la Duchesse Anne. 2 Bouygues Telecom 5G transmitters are listed as technically operational — installed, but not yet declared commercially in service.

2 masts belong to On Tower France and 1 to Totem.

On 3.5 GHz, the fastest 5G band: Free Mobile on 2 of its 3 masts, Orange on 2 of its 4 masts, Bouygues Telecom on its only mast and SFR on its only mast.

Nearby, Saint-Brevin-les-Pins (7.4 km to the north) has 11 masts, more than here.

The widest declared gap between neighbouring supports is about 1.6 km, to the north-east of the centre.

Colocation covers 3 supports.

Among the 65 Loire-Atlantique towns with at least five masts, Saint-Michel-Chef-Chef ranks 62nd by mast count. With 5 masts for 5,714 residents, or 9 per 10,000, it has more masts per inhabitant than the median for those towns (8).
