TV reception troubles can be frustrating—especially when you’re watching your favorite show and the screen goes pixelated or the audio cuts out. One popular fix is a TV signal booster, also known as a TV amplifier. But is it the right solution for you?
In this post, we explain what a signal booster is, how it works, and when you actually need one. If you’re on the Sunshine Coast and dealing with signal issues, this guide from Brocky’s TV will help you make the right call.
What Is a TV Signal Booster?
A TV signal booster is a small electronic device that amplifies digital signals received by your antenna. It strengthens the signal before it reaches your TV, helping to reduce pixelation, freezing, and audio loss.
There are two common types:
- Masthead amplifier – installed close to the antenna (typically on the roof)
- Indoor amplifier – installed between the antenna cable and your TV inside the house
Both types serve the same purpose but are used in different situations.
When Do You Need a Signal Booster?
You may benefit from a signal booster if:
- You live far from broadcast towers (rural or hilly areas)
- You experience pixelation, signal dropouts, or “No Signal” messages often
- Your signal weakens when using a splitter for multiple TVs
- Trees, buildings, or mountains obstruct your signal path
- Your TV picture degrades during cloudy or rainy weather
However, not all signal issues are caused by a weak signal. That’s why it’s important to first identify the root cause before installing a booster.
When You Don’t Need a Booster
Adding a signal booster to a setup that already receives a strong signal can do more harm than good. Over-amplifying the signal can cause interference and distort the picture.
You likely don’t need a booster if:
- You live close to TV broadcast towers
- Your antenna is high-quality and well-positioned
- Your reception problems are caused by damaged cables, poor alignment, or faulty connectors
- Your signal is strong, but some channels still don’t work — in this case, it’s often a tuning issue, not a signal strength issue
In these cases, it’s better to fix the physical setup before adding an amplifier.
How a Booster Is Installed
Signal boosters must be installed correctly to work effectively. For masthead amplifiers, installation is done at the antenna level—usually on the roof—so the signal is boosted before any cable loss occurs.
Here’s how a typical setup looks:
- Antenna picks up the TV signal
- Masthead amplifier boosts the signal at the antenna
- Power supply unit is plugged in indoors and connects to the same cable
- Signal is carried down the cable to your TV or splitter
Indoor amplifiers are easier to install but not as effective in cases of severe signal loss.
Should You Install One Yourself?
While some indoor boosters are plug-and-play, installing masthead amplifiers on rooftops requires technical knowledge and safety precautions.
A professional technician will:
- Measure your actual signal strength
- Identify if a booster is needed
- Install it correctly (and safely)
- Avoid over-amplifying or interfering with nearby signals
- Ensure the signal is distributed evenly to all TVs in your home
If you’re unsure, we recommend having your setup tested before making any changes.
Other Ways to Improve TV Reception
Sometimes a booster isn’t necessary. Here are other effective fixes for weak signal problems:
- Reposition or elevate the antenna for a clearer line of sight
- Replace old coaxial cables (use RG6 for best results)
- Secure all connectors and eliminate corrosion
- Switch to a high-gain antenna for better long-distance reception
- Reduce the number of splitters in your system
These improvements alone can solve 80% of reception problems—without the need for amplification.
