Aerial for DAB Reception
After a bit of recent re-jigging, I now have a single 52-element aerial in the loft, feeding two TV's, two Freeview boxes, and two FM tuners. Our signal strength isn't as good as I'd like (direct feed to a TV/STB reaches little more than 70% - with the whole network plugged in, it dips to mid-50's percent).
Because of this I'm planning on investing in a masthead signal amplifier. But looking into what I need has opened up a can of worms really. I see that some of the amplifiers have FM/DAB inputs as well as the usual UHF inputs, and this got me thinking I might well be glad of a dedicated FM aerial integrated into my aerial network, ready for my addition of a DAB tuner to my stereo setup sometime soon.
But then I wonder whether the 52-element aerial would give a good enough signal once it's been amplified anyway. The wall sockets have seperate TV/FM sockets, so the signal is being split there. Would this be sufficient for DAB? Is it generally accepted that a good DVB signal means a good DAB signal, or is that not the case? If you have access to a good quality (albeit amplified) signal, does a DAB tuner need a dedicated DAB/FM signal, or will a standard signal suffice?
I would say our FM signal isn't all that bad, but there are a couple of stations I can receive in the car when it's on the drive that I can't get indoors. Switching from the simple bundled FM aerial to the roof/loft aerial in the past has never offered an improvement in quality or more stations either.
