It's possible, especially if there are large trees near your TV aerial. The TV signal travels in a straight line from the transmitter to the aerial and does not bend well around large objects such as trees. You may notice a change in signal strength and quality between spring and autumn, as the trees gain or lose their leaves. The signal may fluctuate in wet or windy weather. In the summer, when trees are in full leaf, they can act as a barrier to the signal, resulting in a 'snowy' or grainy picture on analogue TV. Trees can also affect the signal and cause 'ghosting'. On digital TV the picture may break up or freeze.
You should make sure that your aerial is aligned correctly to the direction of the signal from the transmitter, and it may need to be installed so that it is above the level of the trees. An aerial installer will be able to advise. You can go to the CAI (Confederation of Aerial Industries) or Registered Digital Installers sites to find a registered installer in your area.
You could also consider switching to a different digital TV service. Please visit the Digital UK website for information about digital TV services in your area.
