Signal problems In the hot weather

[andy120]

Basically, everytime it gets hot or very sunny i lose freeview signal. Then when it cools down agiain in the evening the signal returns. Just wondering if anyone else has come across this problem and knows how to resolve it.

I do have woods at the back of the house,with tall tree's. But the signal is perfect all throughout the winter ect, maybe just coincidence but only seems to happen on sunny days.
