1 church or religious building and 7 pylons, 1 building and 1 lighthouse or signal station carry the commune's antennas.

Place names on the register include Le Val Saint-Martin, La Birochere, Le Port, Port de la Noëveillard, Ste-Marie and 5 rue André-Marie Ampère.

15 systems were switched on in the past 12 months. ANFR has approved 2 new sites that are not live yet, plus additions on one existing mast. New: Bouygues Telecom (3G, 4G and 5G) at L'Herberdière, Free Mobile (4G and 5G, including 5G at 3.5 GHz) at 2 Rue Saint Gilles and SFR (3G, 4G and 5G) at L'Herberdière. 8 Bouygues Telecom 5G transmitters are listed as technically operational — installed, but not yet declared commercially in service.

The highest support stands 79 m at Le Sandier (pylon). The median is 29 m, slightly below the Loire-Atlantique median of 32 m.

The commune owns 3 of the 10 masts, Totem owns 2.

2016 was the busiest year, with 28 new systems, most of them 4G. Orange opened 5G here in October 2021; Free Mobile followed in November 2021, Bouygues Telecom followed in April 2022. The oldest transmitter still listed here goes back to 1999.

Of the 10 masts in the commune, 2 masts carry all four networks, and Orange is the only carrier on 3 masts.

Supports leave a gap of about 6.6 km to the east of the centre. Most declared azimuths point outward, along a corridor or valley rather than at the centre.

3.5 GHz 5G is declared by Orange on 6 of its 7 masts, Bouygues Telecom on 3 of its 5 masts, Free Mobile on 3 of its 4 masts and SFR on 3 of its 5 masts.

Saint-Michel-Chef-Chef lies 8.3 km to the north-west and has only 5 masts.

By mast count, Pornic is 15th of the 65 Loire-Atlantique towns that have five or more. With 10 masts for 18,745 residents, or 5 per 10,000, it has fewer masts per inhabitant than the median for those towns (8).

18,745 residents over 95 km²: supports are mostly pylons, not rooftops. It is part of the CA Pornic Agglo Pays de Retz intercommunal grouping.
