2 water towers and 14 pylons and 12 buildings carry the commune's antennas.

Place names on the register include Kerthomas, Le Parc du Golfe, 21 rue des Frères Lumières, boulevard Georges Pompidou, 28 rue Winston Churchill and rue Alain Gerbault.

The commune owns 2 of the 28 masts, Totem owns 8.

2021 was the busiest year, with 70 new systems, most of them 5G. Local 5G started with Free Mobile in December 2020; Orange followed in July 2021, Bouygues Telecom followed in September 2021. The oldest transmitter still listed here goes back to 1995.

55 systems were switched on in the past 12 months. Approved additions not yet in service are pending on 10 existing masts, for example Bouygues Telecom (5G 3.5 GHz) at Z.i. du Prat, Bouygues Telecom (4G and 5G, including 5G at 3.5 GHz) at rue Alain Gerbault and Bouygues Telecom (3G 900 MHz) at Le Fourchene. 20 Bouygues Telecom 5G transmitters are listed as technically operational — installed, but not yet declared commercially in service.

ANFR lists a 77 m water tower at Z.i. du Prat as the tallest structure. The median is 31 m, slightly below the Morbihan median of 35 m.

Of the 28 masts in the commune, 4 masts carry all four networks, and Orange is the only carrier on 8 masts.

By mast count, Vannes is 1st of the 35 Morbihan towns that have five or more. With 28 masts for 55,790 residents, or 5 per 10,000, it has fewer masts per inhabitant than the median for those towns (10).

3.5 GHz 5G is declared by Orange on 13 of its 18 masts, Free Mobile on 10 of its 14 masts, Bouygues Telecom on 9 of its 12 masts and SFR on 8 of its 12 masts.

Supports leave a gap of about 2.4 km to the east of the centre.

14 km to the south, neighbouring Sarzeau has only 12 masts.
