Hi there, postcode B721bY
we are lined up to the Sutton Coldfieldtransmitter and getting some interference on C40 BBCB TV channels. We get more interference when its rainy or windy but also when its not. Its not all the time and doesn't affect any other channels.
The TV says strength approx 80-95%, quality approx 70-100%. The signal gets grainy when quality drops to 70-80%.
The aerial is a class 1 W type in the loft. It has high quality cabling in the loft to a powered amp that splits the signal to 8 tv points in the house. Ive tried a variable attenuator which helped a bit but didn't cure the issue.
Can you advise what would cause the interference on C40 channels only and not the others?
