Check that the reported problem fits the service
Restore TV’s diagnostic route concerns new interference to free-to-view television received through an aerial, potentially associated with upgraded mobile masts. Pixelation or no signal can also have other causes. Use the service’s diagnosis and check transmitter work rather than assuming that a nearby mast explains every reception failure.
Identify whether an amplifier is present
The service’s fitting information distinguishes a simple aerial-to-television path from an installation with a loft or rooftop amplifier. With an amplifier, it says the filter belongs between the aerial and amplifier. Putting a filter only at the television may therefore be the wrong arrangement for that system, even if it appears to fit the available socket.
Use the supported installation route
Restore TV describes a weatherproof fitting for rooftop amplifiers and possible engineer assistance subject to its eligibility conditions. Do not climb to an aerial or alter a communal system to reproduce a generic diagram. Explain whether the installation is individual or shared, and where the amplification occurs. The responsible managing agent or service can then advise on the actual route.
Check the result without broad promises
If a filter is supplied, follow the included instructions and compare the affected services afterwards. A filter addresses specified mobile-signal interference; it is not a repair for every broken aerial, cable or transmitter fault. Keep a note of the original symptom and the change. If reception remains poor, tell the service what was installed and where, rather than adding multiple filters without a diagnosis.
Questions, answered
Does the same fitting position apply with and without an amplifier?
No. Restore TV specifies placement before an amplifier.
Does every aerial problem establish eligibility for an engineer visit?
No. The service publishes eligibility and diagnosis conditions.
