Mobile Signal Booster Installation Melbourne Equipment Measured Before & After.
Weak mobile reception indoors is almost never a phone problem. It is a building problem, and the fix depends entirely on whether there is usable signal outside to work with. We measure the signal at your property first, then install a carrier approved booster only where it will genuinely help. Where it will not, we say so and point you at what will.

Measured, Installed and Verified Across Victoria
A booster does one thing. It takes signal that already exists outside your building, amplifies it, and re broadcasts it inside. That single sentence explains why some installations transform a property and others do nothing at all. If there is decent signal in your driveway and none in your kitchen, a booster is exactly the right answer. If there is no signal anywhere on the block, no amount of hardware will create some.
This is why we measure before we quote rather than after. We take readings outside and inside, at the positions that matter, on the carrier your household or business actually uses. Those readings decide whether we recommend a booster, how much gain it needs, and where the antennas have to sit. They also decide when we tell you not to bother, which happens often enough that it is worth saying out loud.
Why Boosters In Australia Must Be Carrier Approved
This is the part of the job that matters most and the part almost nobody explains. In Australia it is an offence to operate a mobile phone repeater unless the device is approved and supplied through a carrier. Generic repeaters sold online, including the ones advertised as boosting Telstra, Optus and Vodafone all at once, are prohibited devices here.
The reason is interference. A poorly designed repeater does not just help you, it degrades the network cell serving everyone around you, and carriers can and do trace them. Penalties fall on the person operating the device, not the person who sold it, which is worth knowing before something goes on your roof.
In practice this means a legal booster is matched to one carrier’s spectrum. You nominate the network that matters most to your household or business and the unit is configured for it. If someone has quoted you a cheaper multi carrier unit, that is why the price is different. We install carrier approved equipment only, and we will tell you at the assessment which carrier the unit needs to match.
Every installation starts with a free signal test and a fixed written price. If the measurement says a booster will not help, we tell you rather than sell you one. Call 1300 520 116 or book a test below.
What Changes The Price Of A Booster Installation
The hardware is only part of it. These four decide the figure, and all four are established at the free signal test.
How much signal there is to work with
- Strong outside signal needs less gain and simpler hardware. A weak fringe signal needs a higher gain unit and a far more careful donor antenna position.
How much area needs covering
- One room is one internal antenna. A two storey house, a warehouse or a basement needs several on a splitter, plus the cabling between them.
The roof and the cable path
- Tile, tin, slate or a commercial roof each mount differently, and the run from the donor antenna down to the unit has to be sealed and dressed properly.
Materials that block signal
- Metal cladding, concrete, foil backed insulation and double brick all attenuate signal, which changes how many internal antennas the same floor area needs.
Every building is priced individually after a free signal test, in writing, with nothing to pay if you decide not to proceed. If an existing booster has stopped working rather than never having worked, our service and repair team takes on systems installed by others.

Where The Antennas Actually Go In A Building
A booster is two antennas and a cable between them. Where each one sits is the entire design, and the separation between them is what makes it work rather than shut itself down.
Donor antenna, roof
The highest point with the clearest path to the tower, which often is not the side you’d expect. We find the tower direction by measurement, not assumption.
Best for:
Every installation starts here
Service antenna, ceiling
Central to the area needing coverage and far enough from the donor that the two do not hear each other. Too close and the system oscillates and shuts down.
Best for:
Single storey homes and small offices
Multiple internal antennas
Two storey homes, long warehouses and basements need several service antennas on a splitter, each covering its own zone with a controlled overlap.
Best for:
Large homes, warehouses, multi level
Cable run and separation
Vertical separation between roof and ceiling antennas does most of the work. Cable length and quality matter too, because loss in the run eats the gain you paid for.
Best for:
Every installation
The booster unit
Mounted for easy access, short cable runs, and proper power and ventilation. Fully carrier approved and configured to your network.
Best for:
Homes and commercial sites
Warehouse and industrial
Metal cladding and racking block signal in ways an open floor does not. Several internal antennas positioned along the span rather than one in the middle.
Best for:
Warehouses, factories, sheds
Fault finding on existing systems
Boosters that worked and then stopped, usually feedback from antennas mounted too close, or a prohibited device that needs replacing with legal equipment.

Systems installed by others
Where we install
Melbourne Buildings We Install Boosters In
The hardware barely changes between these. What changes is how many internal antennas the building needs and where the donor has to sit.
Metal roofed and clad homes
Colorbond and metal decking reflect mobile signal effectively. Common on newer builds and the reason many owners have full bars outside and none inside.
Basements and underground offices
Concrete and depth together kill reception. These need the most careful internal design and give the most dramatic result.
Warehouses and industrial sheds
Long spans, metal cladding and racking that blocks signal. Several internal antennas rather than one central unit.
Rural and acreage properties
Distance from the tower rather than building fabric. Where there is nothing usable outside at all, we will say so before quoting.
Double brick and rendered homes
Solid walls plus foil backed insulation, which together stop signal at the front rooms and leave the back of the house dead.
Retail and hospitality venues
Payment terminals, staff phones and customer expectations, in buildings often built with signal blocking materials.
We Measure First. Then We Tell You The Truth.
The signal test is free and it is the most useful half hour in this whole process. It tells you whether a booster will transform your reception, make a modest difference, or do nothing at all. We would rather you knew that before you spent anything.
What Decides Whether A Booster Works
What is the most important part of a booster installation? The separation between the two antennas, not the unit between them. A booster with the donor and service antennas too close together hears its own output, oscillates, and shuts itself down to protect the network. That single design decision is behind most of the failed installations we are called out to inspect, and it is why the survey matters more than the hardware brand.
Main Components
Donor Antenna
Mounted outside, aimed at the serving tower. Directional, because pointing it correctly is worth more gain than paying for a bigger unit.
Booster Unit
Carrier approved amplifier matched to one network’s spectrum. Mounted where it can be serviced and ventilated.
Service Antenna
Indoors, re broadcasting the amplified signal across the area that needs it. Ceiling or wall depending on the space.
Coaxial Cable
Low loss cable between the antennas and the unit. Length and quality directly reduce the gain reaching your rooms.
Splitters
Divide the output across several internal antennas on larger sites, sized so each zone still receives usable level.
Sealed Roof Entry
Where the donor cable enters the building. Flashed and sealed, because this is where water gets in on a poor install.
Mounting Hardware
Pole, bracket or non penetrating frame chosen for the roof type, fixed to structure that will not move in wind.
Lightning Arrestor
Protects the unit and the building where the donor antenna is the highest point on a rural property.
Power Supply
Positioned so the unit can be isolated for service without pulling the whole system apart.
Before And After Readings
Measurements taken at the same positions pre and post install, handed to you so the improvement is documented rather than claimed.
Advanced & smart features available
- Carrier approved equipment only
- Readings taken before and after
- Tower direction found by measurement
- Antenna separation designed in
- Sealed and flashed roof entry

From Signal Test To Verification
The same four steps whether it is a single storey home or a metal clad warehouse.
Free signal test
We measure outside and inside at the positions that matter, on your carrier. These readings decide everything that follows, including whether we recommend proceeding at all.
System design
Donor position, internal antenna count and placement, cable route and unit location, written up with the readings that justify each decision.
Installation
Antennas mounted, roof entry sealed, cable run and dressed, unit installed and configured to your nominated carrier by registered cablers.
Verification
We measure again in the same positions and show you the difference. If the improvement is not there we adjust rather than leave you to discover it.

Before you buy hardware
A Booster Or Wi Fi Calling?
Two different fixes for what feels like the same problem. One needs hardware and one may already be sitting in your pocket, and it costs nothing to find out which applies to you.
Carrier Approved Booster
Recommended
What it fixes
Actual mobile signal, so calls and cellular data both improve throughout the covered area.
What it needs
Usable signal outside the building to amplify, plus a roof position and a cable path.
Where it wins
Properties where outside signal is fine and the building is blocking it. Warehouses, basements, metal roofs.
Where it fails
Sites with no usable outside signal. Amplifying nothing produces nothing.
Cost
Hardware plus installation, quoted after a signal test.
What we recommend
Where the readings show real signal outside and a building that is blocking it.
Where the readings support it, this is the fix that genuinely changes a property. We will not sell you one where Wi Fi calling would have done the job.
Wi Fi Calling
Alternative
What it fixes
Call quality and SMS over your internet connection. Does nothing for cellular data away from Wi Fi.
What it needs
A solid internet connection and a phone and plan that support the feature. No hardware at all.
Where it wins
Homes with good internet and poor reception, where calls are the main complaint.
Where it fails
During an internet outage, and anywhere in the property Wi Fi does not reach.
Cost
Usually free with the plan, though it depends on the carrier and handset.
What we recommend
We will tell you to try this first when it looks like the simpler fix. It costs you nothing.
Equipment We Install
Carrier approved hardware only, sourced through the proper channels so the device is legal to operate and supported if it fails. If a quote you have received names a multi carrier unit, that is worth a second look before you accept it. The wider hardware range is listed on our equipment and supplier page.
Cel-Fi GO
The carrier approved standard in Australia for homes, offices and vehicles. Configured to one network and widely supported by the carriers.
Cel-Fi QUATRA
Active DAS for larger commercial buildings, warehouses and multi level sites where a single unit cannot cover the floor area.
Carrier smart antennas
Supplied directly through the network for specific residential situations. We install and align them properly.
Directional donor antennas
Yagi and log periodic types selected for the tower distance and direction found during the survey.
Dome and panel antennas
Ceiling domes for open areas and wall panels for corridors and long spans, matched to the coverage plan.
Low loss coaxial cable
Cable grade chosen for the run length, because loss between the antennas directly reduces the gain reaching your rooms.
What People Tell Us Before We Measure Their Site
Most people don’t call about a booster because it sounded interesting. They call after one of these happens, or once they realise it’s coming.
Full bars in the driveway, nothing in the kitchen.
We bought one online and it worked for a week then stopped.
The shed is two hundred metres from the house and there is no signal out there at all.
The installer never measured anything, he just put it up.
The first is building fabric and it is exactly what a booster is for. The second is usually either a prohibited device or feedback from antennas mounted too close together. The third may not be a booster job at all. The fourth is the reason we lead with measurement, because a system designed without readings is a guess with a price tag on it.
What Our Clients Say
Borderless Solutions helped us choose the right cameras and alarm for our property. No pressure, just honest advice and great installation.

Signs Your Current Booster Needs Attention
Boosters rarely fail quietly. They either shut themselves down to protect the network or they slowly stop making a difference, and both leave signs worth checking.
- It worked at first and then stopped
- Indicator lights showing a fault or shutdown

- No readings were ever taken at installation
- Coverage in one room only despite a whole home promise
- Cable entering through a window or under a seal

Mon–Sat 8am–6pm
Are mobile signal boosters legal in Australia?
Only when the device is approved and supplied through a carrier. Generic repeaters bought online are prohibited devices under Australian radiocommunications law, including the multi band units advertised as boosting every network at once. Operating one is an offence and it interferes with the surrounding network, which is how they get traced. We install carrier approved equipment only.
Will one booster cover Telstra, Optus and Vodafone together?
No, and anything sold on that promise is worth a second look. Legal boosters here are matched to one carrier’s spectrum, so you nominate the network that matters most and the unit is configured for it. If people in the building are split across carriers, raise it at the assessment because it changes the recommendation.
How long does the installation take?
A straightforward single storey home is usually two to three hours including the signal test, antenna mounting, cabling and the post install measurement. Warehouses, basements and multi storey buildings needing several internal antennas take longer, and the timeframe is written into the quote before we start.
Will a booster fix reception in a metal roofed house?
Usually yes, and metal roofed homes are one of the clearest cases for one. The metal is what blocks the signal, so putting the donor antenna outside above it and feeding signal in solves the actual problem. We measure first to confirm there is enough outside to work with.
Will it work in a basement or underground car park?
Yes, and these give the most obvious improvement. They also need the most careful design, because the donor is a long way from the service antennas and the cable run has to be planned so loss does not eat the gain.
What if there is no signal outside my property at all?
Then a booster is not the answer and we will tell you rather than sell you one. A booster amplifies existing signal, it does not create it. On rural properties in that position, satellite internet plus Wi Fi calling is usually the workable path, and we install that too.
Can Wi Fi calling fix this instead?
Sometimes, and it costs nothing to try. With a solid internet connection, Wi Fi calling routes calls over it and can solve indoor call quality with no hardware at all. It does not help cellular data, and it depends on your handset and plan supporting it. We raise it at the assessment where it looks like the simpler fix.
Do you install boosters in vehicles or caravans?
Our work is fixed premises. Vehicle and caravan units are a different product with different approval requirements, so we do not fit them. For a permanent installation at a property we are the right call.
Will it improve data speed as well as calls?
It improves the signal, which usually improves both. How much depends on network congestion at your location, which no booster can change. If the tower serving you is saturated at peak times, better signal will not remove that, and we are upfront about it.
Do you service boosters installed by someone else?
Yes. The most common faults we find are antennas mounted too close together causing the unit to shut down, and prohibited devices that need replacing with legal equipment. Tell us the make and model and we will say honestly what can be salvaged.
Why do you measure before quoting?
Because the readings decide the design and sometimes decide against the job entirely. Gain required, antenna positions, how many internal antennas and whether there is anything worth amplifying all come from measurement. A quote given over the phone is a guess about a building nobody has visited.
What do I get at the end of the job?
A working system, the before and after readings taken at the same positions, and documentation of what was installed where. If the improvement is not there we adjust the system rather than leaving you to discover it later.
