Most aerial faults have one of six causes
Thirty years on Surrey rooftops tells you what's usually wrong before you even get there:
- Corroded F-connector at the wall — most common Surrey fault
- Water ingress in the coax at the cable entry
- Storm-bent aerial elements or snapped mast
- Wrong grouped aerial after a transmitter retune
- Failed distribution amp (signal on one TV, dead on others)
- Tree growth blocking line of sight to Crystal Palace
