¶ NOTE: After the PSB multiplexes switch at Nottingham, the commercial multiplexes will use temporary frequencies for some months before adopting their final frequencies and powers. During this transition period, the commercial multiplexes will use the following frequencies: SDN ch 67 (40W), Arqiva A ch 63 (40W), Arqiva B ch 59 40W).

Colour bands denote aerial groups: Red:A Yellow:B Green:C/D Brown:E Grey:K Black:Wideband

Notes

'Out of group' frequencies are marked with a star. Analogue power output 2,000 Watts, post switchover average digital multiplex output will be 343 Watts.

To receive signals from this transmitter, the aerial must be mounted for vertical polarization - the elements going from top to bottom.

Before switchover, the public service broadcasting multiplexes were 1, 2 and B; afterwards they were first PSB1, 2 and 3 but now called BBCA, D3+4 and BBCB. The commercial multiplexes A, C and D had initial post-switchover names COM4, 5 and 6; now they are SDN, ArqA and ArqB. At switchover BBCA, ArqA and ArqB will switch from 16QAM to 64QAM mode transmission, so five multiplexes will transmit in the 64QAM (2/3) 8k mode. BBCB is used for Freeview HD (DVB-T2, 256QAM), and has a pre-switchover service on selected main transmitters.

Upgrade to Wideband aerial requried to watch all Freeview channels during dual running of analogue and digital television. After switchover, you will have needed to upgrade to a Wideband aerial to receive some or all digital television services.
