A TV signal amplifier, also known as a signal booster, is an electronic device designed to improve the strength and quality of television signals received by your antenna. It works by amplifying the signal before it reaches your TV, helping to reduce pixelation, freezing, or loss of channels—especially in areas far from broadcast towers or where obstacles like buildings and hills interfere with reception.
Signal amplifiers are available in various forms, including indoor plug-in models and outdoor masthead units. The primary function of all these devices is to compensate for signal loss that occurs due to long cable runs, signal splitting, or weak incoming signals.
Not every TV setup requires an amplifier. Consider using a Crest TV signal amplifier if:
- You live more than 10 km from the nearest TV transmission tower.
- You experience frequent pixelation, weak signals, or missing channels.
- Your antenna cable runs are long, causing signal loss.
- You need to split the signal to multiple TVs.
Caution: If you live very close (within 10 km) to a transmission tower, using an amplifier may cause signal overload, resulting in worse reception. In such cases, turn off the amplifier or use a non-amplified antenna.
Before you begin, gather the following:
- Crest TV signal amplifier (model-specific)
- Compatible TV antenna (indoor or outdoor)
- Coaxial cables (ensure good quality with solid copper center conductor)
- Power adapter (usually included)
- Screwdriver (for adjustable gain models)
- TV or digital set-top box
- Wall fixings (if wall mounting)
- Electrical outlet
Optional: F-connectors, insulating tape (for outdoor/masthead installations), cable ties.
Most Crest amplifiers come with:
- The amplifier unit
- Power adapter
- Coaxial cables or ports
- Mounting stand or wall fixings (for some models)
- User manual
Before you begin, check the contents of your package to ensure all necessary parts are present and undamaged.
- Indoor Amplifiers: Place as close to the antenna as possible for best results. Avoid placing near sources of electrical interference (microwaves, computers, gaming consoles).
- Outdoor/Masthead Amplifiers: Install near the antenna, ideally on the mast or in the loft. Use weatherproofing if outdoors.
Proper location is critical. The closer the amplifier is to the antenna, the less signal is lost before amplification. If you have a long cable run between your antenna and TV, installing the amplifier near the antenna will maximize its effectiveness.
Tip: Placing the antenna near a window and pointing it toward the nearest transmission tower can significantly improve reception.
1. Connect the Antenna:
- Plug the incoming antenna cable into the “ANT” or “IN” port on the amplifier.
2. Connect the TV:
- Run a coaxial cable from the amplifier's “TV” or “OUT” port to your TV or set-top box.
3. Power Up:
- Plug the power adapter into the amplifier and then into a wall outlet. Switch on the amplifier.
1. Cut the Aerial Cable:
- Where you want to install the amplifier, cut the existing cable and fit F-connectors to both ends.
2. Connect to Amplifier:
- Attach the aerial input cable to the amplifier's input, and the output cable(s) to the output(s).
3. Install Power Supply:
- Install the power supply unit indoors, connecting it in-line with the coaxial cable before it reaches your TV. Plug into mains power.
- Turn on the amplifier.
- Power on your TV and run the “auto-tune” or “channel scan” function to let the TV detect available channels.
- If you adjust the antenna or amplifier gain, re-tune the TV each time to ensure optimal channel detection.
- Many Crest amplifiers feature a gain control dial. Use a small screwdriver to adjust the gain:
- Increase gain if you're far from the tower.
- Decrease gain if you notice pixelation or channel dropout (possible signal overload).
- Experiment with antenna placement and orientation for best results.
- Always keep the amplifier and antenna away from sources of electrical interference.
Signal loss, also known as attenuation, occurs naturally as the TV signal travels through coaxial cables and splitters. The longer the cable, the more signal is lost before it reaches your TV. Splitters, which divide the signal to multiple TVs, also contribute to signal loss.
A Crest TV signal amplifier compensates for this loss by boosting the signal strength, ensuring that your TV receives a strong, clear signal. However, amplifiers cannot create a signal where none exists—they can only enhance what is already present. If your antenna isn't receiving a signal, no amplifier will help until the antenna is properly positioned or upgraded.
To get the most out of your Crest amplifier, consider these optimization tips:
- Antenna Placement: Elevate your antenna as high as possible and position it near a window or an exterior wall facing the broadcast tower.
- Cable Quality: Use high-quality coaxial cables with solid copper conductors to minimize signal loss.
- Minimize Splitters: Each splitter reduces signal strength. Use the fewest possible, and always amplify before splitting if multiple TVs are involved.
- Avoid Interference: Keep cables and amplifiers away from large metal objects and electronic devices that may cause interference.
- Regular Scanning: Periodically re-scan for channels, especially after adjusting the antenna or amplifier, as new channels may become available or existing ones may move frequencies.
- Using Low-Quality Coaxial Cable: Cheap cables with copper-clad steel or brass conductors may not deliver enough voltage to power the amplifier, leading to premature failure. Always use cables with a solid copper center conductor.
- Signal Overload: If you live close to a transmission tower, too much amplification can cause signal dropout. Reduce gain or turn off the amplifier in such cases.
- Improper Placement: Placing the antenna or amplifier near electronic devices or large metal objects can cause interference. Always keep them away from such sources.
- Loose Connections: Ensure all coaxial connections are tight and free from corrosion. Replace damaged cables or connectors.
- Incorrect Power Supply: Using the wrong power adapter can damage the amplifier or reduce its effectiveness. Always use the adapter supplied with your Crest amplifier.
- Periodically check all cable connections for tightness and corrosion.
- Keep the amplifier and cables clean and dust-free.
- If using an outdoor amplifier, inspect for weather damage and reseal as needed.
- If you notice a drop in performance, re-tune your TV and adjust the gain as necessary.
- Replace any damaged cables immediately to prevent signal loss or amplifier failure.
If you have a large home or wish to distribute the signal to multiple TVs, consider these advanced strategies:
- Distribution Amplifiers: For setups with more than two TVs, use a distribution amplifier designed to maintain signal strength across multiple outputs.
- Cascading Amplifiers: In rare cases with exceptionally long cable runs, you may need to cascade two amplifiers. However, this should be done cautiously to avoid over-amplification.
- Balancing Gain: When distributing to multiple TVs, balance the gain so that all TVs receive adequate signal without overload.
- Professional Installation: For complex setups, such as multi-story homes or commercial buildings, consider hiring a professional installer to ensure optimal performance and compliance with local regulations.
Installing a Crest TV signal amplifier is a straightforward process that can greatly enhance your TV viewing experience by improving signal strength and picture quality. By following the step-by-step instructions, using high-quality cables, and tuning your setup for optimal performance, you can enjoy clear, uninterrupted TV reception. Remember to avoid common mistakes, perform regular maintenance, and consult the FAQ section below for quick solutions to common issues. With the right approach, your Crest amplifier will provide years of reliable service and superior television enjoyment.
If you live within 10 km of a transmission tower and experience pixelation or loss of channels after installing the amplifier, turn off the amplifier or reduce the gain. Too much amplification can overload your TV receiver, blocking reception.
Yes, you can use a Crest amplifier with multiple TVs by connecting it near your distribution amplifier or antenna line splitter. Make sure the amplifier is compatible with your setup and that all connections are secure.
Check that the power LED on the amplifier is lit. After installation, run the auto-tune function on your TV. If you receive more channels or improved picture quality, the amplifier is working. If you notice no improvement or worse performance, check connections and adjust gain as needed.
Yes, always re-tune your TV after installing or adjusting the amplifier or antenna. This ensures your TV recognizes all available channels with the improved signal.
- Ensure all connections are secure and cables are undamaged.
- Move the antenna to a different location, preferably near a window and away from electronic devices.
- Adjust the gain control if available.
- If problems persist, you may need a stronger antenna or an outdoor solution, especially if your home is far from the transmission tower or obstructed by hills/buildings.
