To receive Freeview from the Rowridge transmitter you will require an aerial of group A positioned horizontally. This transmitter is 260 metres above sea-level, and transmits at 20,000 watts.

Full list of Freeview transmitters.

Self-help relays

Self-help relays are transmitters that are not owned by the broadcasting and transmission companies, but by the local users. An active deflector (AD) re-transmits the analogue broadcasts on the same frequencies as the original broadcasts, while a transposer (T) transmits the received broadcasts on different frequencies.

¶ NOTE: Rowridge COM multiplexes are expected to remain on their pre-switchover channel allocations (30, 37 & 33) for a short period after digital switchover NOTE: Rowridge will broadcast both horizontally and vertically polarised signals for all six multiplexes after switchover.

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 500,000 Watts, post switchover average digital multiplex output will be 150,000 Watts.

To receive signals from this transmitter, the aerial must be mounted for horizontal polarization - the elements going from left to right.

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.

After switchover an existing group A aerial will provide all digital TV services.

405-line VHF black and white TV

From the Rowridge transmitter, BBC One was broadcast on VHF C3. In the United Kingdom, 405-line television was used from 1936-39 and 1946 until 1982-85.
