TV aerial for DAB radio?

[primetime]

Have confirmed what I was trying to get a signal from was indeed the old virgin connection which is redundant. The coax externally down the house disappears into the wall about 3 inches from the virgin cable. It doesn't appear internally and potentially is behind a 2 gang socket Will investigate further during daylight hours when I can isolate the electrics.

Feeding the output from a TV aerial into an FM or DAB radio is one of those things that shouldn't work well in theory, but I bet you there are many people out there who have done this and it might work fine, or it might not - there are just too many variables - blame the black art of RF.

I have the set-up Lucid suggests - a TV aerial and a radio areial (a half wave FM dipole) which picks up both FM well enough for my ear and DAB with no breaks or glitches. These are diplexed down a single downlead and undiplexed in various locations in the house as required.

If you find yourelf listening to more DAB and less FM (or in a post terrestrial FM world), you could 'convert' this to a more DAB tuned set-up by cutting the length of the dipole in half.

The loss across a diplexer is lower than a splitter, so it's more signal efficient too.

Just make sure the diplexers you buy can pass the full spectrum of FM and DAB (88-230 MHz) on the 'radio' leg.
