The highest support stands 45 m at Alé Faü (pylon). The median height of measured supports is 36 m.

Every mast here is owned by a tower company rather than by a carrier. Mix: TDF (1), Hivory (1) and ATC France (1).

Fast 3.5 GHz 5G is declared by Free Mobile alone, on 1 of its 2 masts.

Systems from 2001 are still on the register. Local 5G started with Free Mobile in December 2020; Bouygues Telecom followed in October 2023, SFR followed in October 2023. 2023 was the busiest year, with 15 new systems, most of them 4G.

The widest declared gap between neighbouring supports is about 4.9 km, to the west of the centre.

Nearby, Languidic (20 km to the south-west) has 8 masts, more than here.

Only one mast carries all four networks.

Among the 35 Morbihan towns with at least five masts, Plumeliau ranks 32nd by mast count. With 5 masts for 4,632 residents, or 11 per 10,000, it has more masts per inhabitant than the median for those towns (10).
