Reduced signal strength on some Freeview channels

[buildersmate]

In the last 3 weeks some of my Freeview channels have become weaker in signal strength and both picture and sound break up. It applies to BBC1,2 and News24. All others are unaffected. I appreciate signal strength can rise and fall according to climatic conditions, but this is continuous and just on three channels. Any explanations?

Sometimes it's engineering work that's the cause, but it seems to have been going on too long for that. Try asking the BBC - they're usually OK about answering such questions.

All aerials are a 'compromise'. Theoretically, for maximum signal strength, you need a a different aerial, precisely matched to the correct frequency, for every single channel. Obviously, that's not possible, so any aerial is going to better at receiving some channels than others.

It seems that your aerial isn't up to the job when it comes to 'pulling in' the signals which it's least well matched to. The fact that this has been the situation for the past three weeks could be due to weather or atmospheric conditions (for example, such things as solar flares) but, if it's been continuous, it's far more likely to be a physical problem with the aerial. The most obvious one is that the aerial may no longer be perfectly aligned with the transmitter, after being battered by the wind. Alternatively, there could be water ingress into the connections between the aerial and the cable.

Either way, it's time for somebody to climb a ladder.

Have you tried a manual re-scan? Sometimes this helps the box re-connect with the signal.

I have lost those channels since the change to GMT from BST and some others channels on Sky too!

The weather has a huge effect on my Freeview. The signal quality is often a better way of seeing what the weather is going to be than watching it itself! :)

Try making sure the aerial you are using covers all the bands for the channels on freeview or is the aerial you have a proper digital aerial and not an analogue or is there a joint in the main incoming cable that could possibly be getting water ingress....
