We had a new digitalaerial fitted to our roof in October. Along with most of the houses in the area this is pointed to Crystal Palace although your map suggests Sandy Heath is more appropriate.
We were receiving all the Freeview HDchannels fine up till the middle of December - the HD signalquality was between 5 and 7 while the SD channels were 10.
From mid December the HD channel quality has dropped significantly. The signal is sometimes lost completely or very low with a high error rate (which is giving us pixellated pictures).
The same engineer came back out. He advised that the aerial was fine as was the signal strength. He suggested the problems may be due to increased interference from Sandy Heath (for the HD channels). When quizzed why it should be happening now he suggested it may be due to the leaves falling off the trees!?
We have not made any changes to the equipment.
The engineer suggested a stronger amplifier which was supposed to "hold" the picture better. However this is giving no improvement and now the signal is mostly rubbish.
All the other SD channels are fine so the only problem is with HD.
The engineers suggested that this may be a continuing problem up till the London switch-over in April.
My questions are as follows:
- is the explanation regarding the drop off is HD signal quality reasonable?
- is there anything that can be done to alleviate it (for example should I consider pointing the aerial to Sandy Heath)
Any assistance you can provide would be most gratefully received.
