Freeview is a very weak signal with only BBC 1 and BBC 2 working rather poorly.

Itv and S4C is non existent.

LL40 1SG

Digital Aerial is in the loft and has been troublefree for years unitil recently .

Have moved TV s around but the poor or No Signal is consistent in each room location.

Link F140 and 8x Distribution Amp Digital compatiblle installed in the loft adjacent to the aerial over 7 years ago.

Any construcive suggestions please.

Douglas Powell: If the problem is common to all outlets, the logical place to start is where they split or above. Could be a loose cable or water getting in. Or the power supply on the amp is going.

Douglas Powell: There are no reported problems with the transmitter. Have you checked that the amplifier is still powered on and hasn't been inadvertently switched off or unplugged? Do you get a signal if you disconnect the incoming aerial feed from the amplifier and connect it directly to the feed going to one of your TVs?
