Aerials, group changes

At Wenove, all muxes move into the analogue aerial group by the end of DSO programme;

At Pontypool all muxes move into the analogue aerial group at DSO;

At all relays, all muxes remain within the analogue aerial group, except at:

Cwmfelinfach and Usk: BBC B is just above the analogue aerial group so reception may be unreliable without an aerial upgrade. As this is the HD mux requiring DVB-T2 receivers, viewers are advised to wait and see before upgrading their aerials.
Rhondda HP: the new channels are below the analogue aerial group. Existing analogue antennas should be satisfactory.

Aerials, communal systems

Channel changes at - Wenvoe, Abercynon, Cwmfelinfach, Aberdare, South Tredegar, Pontypool, Usk, Machen Upper, Rhondda and Crumlin mean that channelised aerial systems will need to be reconfigured at DSO1 and DSO2.

Adjacent transmitter groups
