I have an aerial in the attic which is unreliable in providing a good signal. Sometimes the reception is good but most often becomes pixilated and I get the message 'tv signal is weak or lost'. I am considering buying an indoor aerial for one tv which is not connected to a tv aerial. ( I have recently changed my Wi-Fi provider from BT to Virgin and was able to receive terrestrial tv via BT without it being attached to an aerial) Can you 're commend one which will work well in this situation?
A second tv is connected to the aerial but still does not provide good terrestrial tv. Both tv's are 'smart' and I am able to watch some live tv through iPlayer. Perhaps I need a different tv aerial? Again, perhaps you could recommend one which will improve my situation?

Dianne Jenkins: An indoor aerial is not ideal because the signal is generally better the higher up the aerial is. One could have the best indoor aerial but if the signal is not sufficient where the aerial is sited then it will be of no use.
With respect to the loft aerial, I would be looking to work out why it isn't providing reliable reception. As this is a reception issue, then it isn't possible for us to get any idea of what this might be like without knowledge of your location, preferably in the form of postcode.
In terms of poor reception, then the thing to check first is that the TV is tuned to the transmitter to which the aerial faces, and not some other transmitter. If the TV is found to be tuned to another transmitter then the next step is to correct this. Knowledge of your location would allow us to ascertain which transmitter(s) may be available and offer more specific guidance.
Another variable is that not all transmitters broadcast all channels, so knowledge of your location and which channels it is that you are having difficulty with would allow advice to be given on this.
