Digital Reception for Bridgnorth Area Switch-over 2011
-Wide Band aerials are required to receive both digital and analogue broadcasts, this is why it is necessary to replace existing aerials in most cases
-Most existing aerials are only designed to receive a narrrow band of frequencies . For example one needs a group "A" aerial to receive analogue channels from the Wrekin.
Group A frequenices are channels 21-37 and the Wrekin analogue Channel numbers are 23,26,29,33, and 35, but the digital multiplexes in this area (from the same transmitter) are channels 39,42,45,49,and if your in a favoured location you can also receive multiplex C and D on channels 53 and 57. Therefore you need an wide band aerial that will respond to any frequency between channels 21 and 68
Every main transmitter in the UK transmits 6 digital multiplexes. Each multiplex carries 4 / 6 TV channels and potentially a compliment of radio channels.
Depending on your location you may be limited to the amout of Multiplexes you can receive. In the Bridgnorth Area (excluding Much Wenlock ) potentially we can only receive 4 out of the 6 multiplexes
Sutton Coldfield carries all 6 multiplexes to the
B'north area.The B'north transmitter will still only carry 4 analogue services until switchover in September 2011
