Our post code is CT1 2AR our aerial appears directed towards the Dover transmitter.

In the past few weeks we have been getting intermittant break-up and stop/start reception on some TV channels, e.g.
4 Seven is particularly bad and BBC2 is nearly as bad. Our TV shows signal strength and quality that for most channels is around 80% but for 4 Seven it at best is 25% and fluctuates to very low values.

We have also been getting problems receiving Classic FM on our digital radios which have there own built in aerials.

We had good reception prior to these latest problems. Are you aware of any issues relating to the transmitters or known obstructions that may be causing this?

Thank you so much for a very detailed answer Chris.

I shall investigate the points you raised and hopefully discover the problem.

In answer to some of the points raised I can say:
We do get issues with the co-channels you mention but not as severe.
The aerial is pointed at Dover.
The aerial is secure as is the cable. The connection/amplifier boxes are in good condition and taped against water ingress.
The aerial has not been replaced; it was here when we bought the property in 2013.
As stated earlier there was no issue with reception up to a few weeks ago so I assume the aerial is of the correct type.
We have not had a postcard from

I shall investigate the other points you kindly highlighted, particularly with respect to tuning.

Again many thanks for the expert guidance.
