The short answer
There is no useful single price for every Brisbane antenna job. The scope changes with the property's reception conditions, roof and mounting access, the condition of existing cable and hardware, the number of TV points, and the testing required. Ask for a written scope that separates fault finding, supplied parts, installation, outlet work and any access or making-good costs.
Check whether installation is the right job
Pixelation or missing channels does not prove that a new antenna is needed. ACMA lists damaged antennas, unsuitable antenna type or position, cabling, fly leads, connections, splitters and boosters as possible contributors to poor reception. ABC recommends checking which channels and TVs are affected, loose leads and an accessible fly lead before assuming the rooftop equipment has failed.
Tell the quoting business whether the request is for a new home setup, an extra TV point, a visibly damaged antenna or a reception fault. A fault assessment may end with a connector, outlet or distribution repair. A new installation quote should describe what is being replaced and why, rather than treating every poor picture as an antenna sale.
What changes the scope of a quote?
These factors explain why two properties can require different work. They are not a price list or a diagnosis.
| What you notice | What it may point to | Useful next check |
|---|---|---|
| Signal is weak or inconsistent at the address | Antenna choice, position and testing may need more attention | Use address-level reception information and ask how onsite measurements will guide the choice. |
| Roof is high, steep, fragile or hard to reach | Access and mounting arrangements may change | Describe the roof and ask what safe access and any separate work the quote includes. |
| Existing coaxial cable or mount is damaged | More than the antenna may need replacement | Ask which existing parts can be tested and reused. |
| Several TV points or a shared antenna system are involved | Distribution, splitters and permissions add scope | List working and failed outlets; identify the building-system owner if applicable. |
| Only one television has the problem | An outlet, fly lead or receiver check may come first | Compare the same channel on another TV using safe, accessible connections. |
Reception and equipment selection
ACMA's mySwitch information can show predicted coverage, channels and the antenna orientation for an address. It is a planning input, not a guarantee of the signal measured on your roof. Nearby buildings, trees and the property's distribution path still matter. A technician can test signal level and quality through the antenna, amplifier, splitters, leads and connectors before recommending equipment.
More hardware is not always the answer. ACMA warns that splitters reduce signal level and an unnecessary booster can overload a receiver. Ask whether an amplifier is genuinely needed and whether the quote includes testing at the TV points you use. The result being sought is reliable reception at those points, not just a new antenna on the roof.
Roof access, cabling and TV points
A straightforward reuse of sound cable and a suitable mount differs from a job that needs new coaxial runs, a replacement bracket, extra outlets or difficult roof access. WorkSafe Queensland identifies falls and electrical hazards for roof and ceiling-space work, including antenna installation. The method and any access equipment must be assessed for the property; a photograph cannot settle that on its own.
If you live in an apartment or townhouse, check whether the antenna and risers are part of a shared system and who may authorise work. The cost of a private outlet repair and a shared-system alteration cannot be compared as if they were the same job. Tell the quoting business about body corporate or property-manager access before booking.
What to ask each quote to include
- The fault assessment or new installation work, including any signal testing before equipment is chosen.
- The antenna, mount, mast, cable, connectors, splitters and outlets to be supplied or reused.
- The number of TV points to be connected and tested, and what a successful handover will check.
- Roof access, safe-work arrangements, building permission and any making-good or separate trades.
- The total payable amount, GST treatment, exclusions and how additional work will be approved if inspection changes the scope.
Compare the same work, then decide
A low headline figure may exclude cable replacement, an extra TV point, difficult access or testing. Ask for any assumptions in writing and compare the completed scope. If a business recommends replacement, ask which measured reception or condition finding makes repair unsuitable. If repair is recommended, ask whether the remaining antenna and distribution path are still serviceable.
Example scenario: a Brisbane house has two TVs, but only the bedroom picture breaks up. Testing the bedroom outlet and fly lead may be more relevant than quoting a complete rooftop replacement. That is a hypothetical starting point, not a diagnosis of your property or a report of completed work.
