When Freeview starts pixelating or channels disappear, replacing the aerial is not automatically the correct repair. The fault can be anywhere between the aerial and the television — including external cable, splitters, amplifiers, wall plates and flyleads.
Purpose of this guide
This page helps you identify the pattern of the fault so Wavexa can diagnose it efficiently. It is not intended as a step-by-step repair guide.
What the symptoms can indicate
The pattern matters.
Every TV in the property is affected
The aerial, main feed, amplifier or shared distribution equipment becomes more likely.
Only one TV is affected
A local flylead, wall plate, outlet or branch of the distribution system may be at fault.
Some channel groups are missing
Signal level or quality may be marginal on specific multiplexes rather than there being a total aerial failure.
The problem is worse in rain or wind
External aerial alignment, water ingress or deteriorated cabling may need investigation.
Common causes
What Wavexa would consider during diagnosis.
Aerial alignment or physical deterioration
Water ingress into external coaxial cable
Damaged flyleads or wall plates
Faulty splitters or distribution amplifiers
Poor signal level or excessive amplification
Changes to the local reception environment
Useful information
What to note before Wavexa attends.
You do not need to dismantle or reconfigure anything. These simple observations can make the diagnosis faster:
Whether every TV has the same issue
Which channels are missing or breaking up
Whether the fault is constant or weather-related
Any recent building work, loft work or equipment changes
Whether an amplifier or powered splitter is fitted
Professional diagnosis
How Wavexa approaches the problem.
Wavexa can measure signal strength and quality at the aerial feed, outlets and television position. This identifies whether the correct repair is aerial work, cabling, distribution equipment or simply one local connection.
Need this fault checked?
If Freeview has become unreliable, Wavexa can test the system properly and repair the actual fault rather than replacing parts unnecessarily.
