I don't think it is broadcast from Sandy Heath but from the mast at Madingley which used to provide a C5 analogue service to Cambridge before analogue closure. The mast does currently provide other radio services. The Cambridge TV service area can be seen here: About | Cambridge TV
Click on "Tuning In" to see the predicted service area.

Daughter at NN1 5BT has lost most channels. From what she says, it looks like they only have PSB1, PSB2. The ones they have are subject to break-up.
They have good quality outdoor aerial, and received all channels with good reception until recently.
TV is Sharp LC-32D44E-BK
Any suggestions?

'Sickofyou':
With your signal at 100% strength oit is too strong and the cause of your problems. Reduce the signal strength by fitting an attenuator. The ideal strength is between 60% and 80% with quality above 80%.

Yes, Martini - it is from Madingly - but is pretty strong in Brandon, which is supposed to be well outside the service area ??

If you and your affected neighbours live in a communal block with a shared communal aerial, then yuou should contact the organisation responsible for maintaining the flats as it could well be that the communal aerial system has developed a fault that only they can have rectified.
