The summer has got off to a bit of a shaky start. With above normal temperatures at Easter and just below average temperatures for May, here’s hoping the summer months deliver us lots of blue skies and sunshine.
When we’re blessed with clear skies and soaring temperatures the high air pressure that brings this weather can also affect Freeview signals.
Usually, a signal from a television transmitter can only be received by those homes that have aerials with a direct line-of-sight to the transmitter. On a warm summer day however, the hot air can get trapped under colder air high up, creating a layer which acts like a mirror for television signals, reflecting them back towards Earth. This can cause signals from different transmitters to overlap and result in Freeview interference.
The TV broadcasters can’t prevent it, and adjusting your aerial will make no difference. Reception will only improve when the weather changes.
But the rain is never far away on our island. While we might enjoy lounging in front of the telly during bad weather, your TV signal could be affected by strong winds, unruly tree branches, wet leaves or flying debris – none of which are your aerial’s best friend.
We hope you have a great summer! From the BBQ’s to the beaches and a clear Freeview signal.
If you’ve noticed new interference to your Freeview – there’s a small chance it may be due to 4G mobile signals, rather than the weather. We’re here to help – 0808 13 13 800 (free from UK landlines and mobiles).
