Cell towers in Tarnos (Landes)

Antennas are listed at La Humere, Landes de Cazaubon, 58 Boulevard Jacques Duclos, Chemin de l'Annelongue, 506 rue de l'Industrie and Avenue du 1er Mai.

ANFR has approved one new site that is not live yet, plus additions on one existing mast. New: SFR (4G) at 79 Avenue du 1er Mai. 7 Bouygues Telecom 5G transmitters are listed as technically operational — installed, but not yet declared commercially in service.

The tallest structure is a 46 m pylon at Chemin de l'Annelongue. The median is 34 m, slightly below the Landes median of 37 m.

Every mast here is owned by a tower company rather than by a carrier. Mix: Cellnex (4), Hivory (2) and Totem (1).

Systems from 2005 are still on the register. Free Mobile switched on the first 5G here in May 2021; SFR followed in May 2021, Orange followed in September 2021. 2021 was the busiest year, with 25 new systems, most of them 5G.

Among the 28 Landes towns with at least five masts, Tarnos ranks 8th by mast count. With 8 masts for 12,957 residents, or 6 per 10,000, it has fewer masts per inhabitant than the median for those towns (12).

On 3.5 GHz, the fastest 5G band: Bouygues Telecom on 3 of its 6 masts, Free Mobile on 3 of its 4 masts, Orange on all 3 masts and SFR on all 2 masts.

The widest declared gap between neighbouring supports is about 2.2 km, to the west of the centre.

Nearby, Ondres (2.5 km to the north-east) has less 5G (67%).

Only one mast carries all four networks.

12,957 residents over 27 km²: supports are mostly pylons, not rooftops.

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