This Dolphin base station at Sarisbury in Hampshire, is co-located on a tower for one2one (in the foreground). The two Dolphin sector antennae are located below the one2one antenna cluster and point in each direction along the M27 motorway. The Dolphin cabin is on the right.

The tower in the background appears to be for Orange (above) and BT Cellnet (below).
