    HI there I have just installed a Pioneer DBR-TF100 receiver it is connected to a new loft aerial and I am getting 53 channels all with very good picture but have not been able to get BBC1 & BBC2 when going through the set up I am getting 60-70 % signal strength and it says signal quality good should I be able to get a stronger signal ?

    Thanks Mark

    Is the aerial a wideband one?

    I just installed the Pioneer, had to change mine.

    Also had a peculiar loss of some channels due to RF interferance from another unit!

    Check the channel numbers for your area from the BBC transmitter info site, and see if you have any VCR/Digibox/DVD recorder outputting RF on a similar channel number.

    Sorted mine out.

    My signal 60% to 85%

    regards

    I bought my in-laws a Pace box for Christmas - set it up and it found 87 channels - came as a shock as I was expecting 30!

    The Signal strength was around 60 - 65 % so I was happy with that - BBCs and ITVs were fine quality wise.

    Bit confusing for your area, try this below........

    03. How do I know if I can get DTT and do I need to upgrade my existing aerial?

    UHF channels are numbered 21-68. The type of aerial you will require to receive DTT will depend on the channel frequencies of the transmitter you intend to receive DTT from.

    First check the likelihood of being able to receive DTT in a postcode checker, http://www.freeview.co.uk/canireceivefreeview/index.html or http://www.dtg.org.uk/retailer/coverage.html. You could also borrow a STB from a friend and/or contact a local aerial installer to inquire about the reception of DTT in your area.

    If either postcode checker says you are unable to get DTT, it may still be possible, depending on your location and the terrain. (*) Additionally, if either postcode checker says that you cannot receive certain channels, it may be possible with an aerial upgrade, depending on the power of the missing mux(es).

    (*) Line of sight maps between you and the relevant transmitter can be created here. The NGR values can be obtained from the Streetmap and Wolfbane sites (see below). The height above ground of the distant aerial (m) is the AOD (m) value (preferably the lowest) obtained from the Wolfbane site.

    To find your local DTT transmitters you will need a grid reference from where you live. This can be obtained from http://www.gazetteer.co.uk/index.html or http://www.streetmap.co.uk/streetmap.dll?GridConvert? (enter your postcode, select Postcode underneath, click Convert and use the LR value obtained in the Wolfbane site below).

    Put the grid reference into both of these links: http://www.wolfbane.com/cgi-bin/tvd.exe? and http://www.wolfbane.com/cgi-bin/tva.exe?.

    This will then give a list of both ATT and DTT transmitters in your area.

    Compare the aerial groups of the transmitter you intend to receive DTT from in both of the above links. If the groups are the same you should be able to receive all the Freeview channels, depending whether the strength of each of the muxes is sufficient (many DTT transmitters have muxes transmitting at different powers).

    If the aerial groups are different you will need to upgrade your aerial to receive all the Freeview channels.
