Channel filters

    For a location on the Armagh/Louth border, the setup is an aerial pointed at Divis and Clarmont Cairn comes in strongly on that without any specific aerial.

    I want to amplify the Divis channels (group A) and not the CC signal.



    Presumably this could be achieved with a selective amplifier or by splitting the signal with a filter and amplifying only the group A channels. Then recombining them for the feed into the set.



    Has anyone any suggestions for the easiest way to achieve this? I could get gadgets from Amazon, EBay etc or Dublin, Dundalk or Newry.

    Have you tried just amping the whole lot? CC mightn't be coming in as strong as you think.

    Originally for digital I was using a Freeview HD box and it tolerated amping everything. My new set doesn't need a box, of course, but it doesn't like the amplified Clarmont Signal.

    What's the gain of the amplifier?

    Anyhow, assuming the CC signal level isn't crazy altogether: if it's just the tuner that's affected, & it's not overloading the amplifier, I'd put the amp. back on the existing aerial, & run it to a suitable diplexer, with a 2nd aerial for CC.

    Just use the Group A to Divis with an 18db amp (or no amp) - CC will be fine
