If your TV is persistently suffering from interference, it might not be your mobile phone that’s always to blame. There are, in fact, many things that can affect your TV’s signal and here are just a few of the usual suspects:
Causes from inside your home
Interference from inside your home can be caused by impulse or induction disruption from other mains-powered devices. Variations in the electrical current can disrupt power to Freeview devices for example. You’ll need to identify the culprit by switching off appliances and devices to see what makes an improvement.
Some possible culprits include:
Tumble dryers, refrigerators, washing machines, combi boilers, freezers, vacuum cleaners or water pumps.
A possible solution could be to fit a mains filter device on the mains connection to the Freeview box. It’s also advisable to keep connectors and leads for aerials as far away as possible from the electrical leads.
Other in-house interference
This could come from well-known interference-causing devices such as:
Mobiles phones, baby monitors, walkie-talkies and cordless home phones
To help keep the problem to a minimum, try to place such devices away from your TV and satellite equipment.
This includes interference from the atmosphere and/or weather and can include strong winds, heavy rain and long periods of hot weather and high pressure.
During inclement weather, a TV’s signal can be affected as your aerial might be subject to movement or being knocked by trees for example. If wet leaves fall onto the aerial, this can also cause the signal to weaken. Buying an improved aerial or placing it higher can help.

Outside induction or impulse interference
Sometimes interference is caused by outside activities such as roadworks or even a neighbour mowing their lawn. These actions can cause a fluctuation in the electrical current to your TV or satellite box. Problems can be caused by:
Traffic passing your property, pneumatic drilling and lawnmowers.
Combat such issues by replacing any old cables that are often more susceptible to outside interference.
Radio interference from nearby amateur radios, taxi companies and police radio channels. One possible solution if you are suffering this type of interference is to fit an RF or UHF band pass filter to block it.
Interference from large barriers
Large objects can physically block your signal. This can result in a blocked signal on either a permanent or temporary basis. Examples of this type of problem can be caused by the development of a new building, the growth of trees or construction cranes.
For temporary blockages, the problem should be resolved when the structure is removed. If the blockage is a permanent fixture, fitting an amplifier can improve signal reception.
