There are a few more, although not within walking distance. They seem to point in the general direction of Divis Mountain or Black Mountain transmitters - Black Mountain's freeview transponders are vertically polarised, Divis on the other hand has a much stronger signal. Its freeview transponders are horizontally polarised, but perhaps there is another vertically polarised transponder on it for BT usage? On the first image, there is a mobile mast on the other side of the road, the aerial isn't pointing directly at it. All of the aerials and cabinets have been recently installed, before there was nothing there.
