Aerial directed at Waltham. Aerial engineer recently checked signal
stength (did he say 57db?). We are in a hollow. Aerial is on pole on
T& K brackets on wall. Aerial fed a splitter - to main TV and to
kitchen TV. Splitter removed as main TV is usually using Virgin. That
was also suffering.


57dBuV is actually a very strong signal. Did he measure it after a
masthead amp? Have you got a masthead amp?

No amp. The signal can seem reasonable (as seen on TV) and then it suddenly
drops and the picture breaks up

You are experiencing the Digital Cliff. A half decent aerial installer
should be able to fix that. If not, use Freesat.
