Treat Safety and Fault Scope Before Tuning
If free-to-air reception fails after a Brisbane storm, stay away from fallen lines, damaged electrical equipment, loose roof materials, water near power and any antenna or mast that may contact electrical services. Once the property is safe, map which TVs and channels failed and inspect only from accessible ground-level or indoor positions.
Storm-related reception loss can come from antenna movement, broken elements, water entry, damaged coax, a failed amplifier power supply, interrupted electrical supply or a wider broadcaster issue. Rescanning does not repair those faults and may erase stored channels while the signal is absent.
For inspection and restoration, use TV antenna repairs and upgrades in Brisbane.
Short answer
Do not climb onto the roof. Check whether all TVs and outlets are affected, compare nearby reception, confirm the tuner source and accessible fly leads, and note visible antenna or cable changes from the ground. If reception remains absent, the mast moved, equipment is wet or electrical damage is possible, arrange an appropriate assessment.
The ACMA’s TV reception fault guidance includes antenna condition, direction, cabling, splitters, amplifiers and interference in its checks. A storm can affect several of those components at once.

Immediate Safety Boundaries
Do not approach or touch:
- fallen or low electrical lines;
- a mast or antenna near damaged electrical services;
- wet power packs, outlets or switchboards;
- hanging coax or metalwork;
- unstable roof sheets, gutters or branches;
- flooded ceiling spaces;
- sparking, hot or burnt equipment.
Contact the relevant emergency, network or licensed electrical service for electrical hazards. Television restoration comes after the site is safe.

Identify the Post-Storm Pattern
| Pattern | Possible search area | Safe evidence | |---|---|---| | Every TV lost all channels | Shared antenna, main cable, power, amplifier or external issue | Neighbour check and timing | | One room failed | Fly lead, outlet or branch | Controlled indoor swap | | Picture changes in wind | Mast movement, loose element or cable | Ground-visible movement only | | Fault begins after rain and improves when dry | Water entry or moisture-sensitive connection | Weather log | | Some networks are missing | Frequency-path, tuning or broadcaster issue | Exact network list | | Antenna angle visibly changed | Mount or mast movement | Ground-level photo | | Streaming works, broadcast fails | Antenna/tuner path | Correct input check |
One pattern can have multiple causes. Do not infer a complete repair scope from a photo.

Safe Checks After the Weather Clears
1. Check broadcaster and neighbour reception
Ask a nearby household whether the same services are affected and review broadcaster notices. A wider outage will not be fixed by property equipment.
2. Check the television source
Select TV, DTV, Antenna or Live TV. Power interruptions can cause devices to return to an HDMI input or restart.
3. Check accessible fly leads
Confirm plugs remain seated and leads were not pulled during storm preparation or furniture movement. Replace only with a known-working comparison lead.
4. Compare TVs and outlets
Test a known-working television and lead on different outlets, changing one variable at a time. This separates one branch from the shared path.
5. Check amplifier power
If the property has a known indoor amplifier power injector, confirm from a dry, safe location that it has normal power and has not been unplugged. Do not open it or handle wet equipment.
6. Observe from the ground
Use ground-level photographs to record a changed antenna direction, loose cable, bent element or damaged mount. Do not use a ladder or roof access for diagnosis.
05 / Process
Why Rescanning Is Usually the Wrong First Step
A scan rebuilds the channel list from whatever signal exists at that moment. If storm damage or an outage removes the signal, the scan may delete previously stored services. It also changes the evidence before the physical path is checked.
First record the existing list and signal symptoms. Follow how to rescan TV channels only when the signal is restored and tuning remains the likely issue.

What an Assessment Should Measure
A post-storm assessment can compare:
- predicted transmitter using mySwitch;
- antenna direction, polarisation and physical condition;
- signal at the antenna source;
- loss through the main cable and connectors;
- amplifier power, input and output;
- splitters and branch balance;
- signal quality at required outlets;
- signs of water-related or intermittent failure.
The ACMA’s antenna installer workflow supports testing the installation and distinguishing property faults from external interference.

Repair or Replace After a Storm?
Repair may suit a structurally sound, locally appropriate antenna with a limited connector, cable, power or alignment fault. Replacement may be more appropriate where the antenna or mount is bent, unstable, extensively corroded, unsuitable for the transmitter or part of widespread weather damage.
The recommendation should identify:
- 1the failed component;
- 2the measured effect;
- 3whether damage is local or systemic;
- 4the safe access requirement;
- 5how the finished system will be verified.
Use the repair-or-replace TV antenna guide for the broader lifecycle decision.

Quote-Preparation Checklist
Provide:
- full address and property type;
- storm date and approximate time;
- when reception failed;
- exact affected TVs, outlets and networks;
- whether neighbours share it;
- safe ground-level photos;
- known amplifier and power-supply location;
- visible water or movement pattern;
- recent roof or electrical work;
- access restrictions.
Final scope and quote depend on inspection. Storm timing alone does not prove which component failed.

Frequently Asked Questions
Should I turn the TV system off after a storm?
+
If equipment is wet, damaged, hot, sparking or near an electrical hazard, do not touch it and seek the appropriate electrical safety response. Otherwise, preserve the existing channel list for diagnosis.
Can wind move an antenna enough to lose channels?
+
Yes. Direction, polarisation and structural stability can affect reception, especially where the original margin was limited.
Why does reception return when the weather dries?
+
Moisture at a damaged connection or cable may alter signal performance. A repeating wet-weather pattern still warrants assessment.
Will a booster repair storm damage?
+
No. It cannot repair a broken antenna, wet connector or failed cable, and may amplify noise or overload the tuner.
Can I claim the antenna repair through insurance?
+
Coverage depends on the policy, cause and evidence. Ask the insurer what documentation it requires; this guide does not interpret insurance terms.
