Can’t take dropped calls and unreliable Internet connectivity anymore? A 4G signal amplifier, aka a cellular repeater, comes as game-changer. But the amplifier itself is only half the job. The antenna for the 4G booster plays an important role in the effectiveness of the whole system. We will explain how to pick the right antenna for your 4G and maximize coverage area and network performance.
Why is the antenna essential for the 4G mobile booster?
A 4G signal amplifier captures a weak LTE signal strength from a cell tower, boosts it, and sends it to the area to cover, where its antenna acts as the eyes and ears of the system. A poorly selected or improperly installed antenna limits the effectiveness of your 4G signal booster kit, bringing in a lot of disadvantages in the long run.

Understanding different types of 4G antennas
Choosing the right 4G antenna depends on the distance to the cell tower, the level of interference, and the area you need to cover: indoor or outdoor coverage. An overview of the most common types is provided below:
- Omnidirectional antennas send signals in all directions and provide 360-degree coverage. They are perfect in situations where the cell tower is unknown or when you need to cover a large and open area. Examples of such solutions include a whip antenna and a magnetic mount antenna, which are used as indoor antennas for 4G repeaters.
- Directional antennas focus their signal in a specific direction, delivering a stronger signal and longer range. They fit the bill when you know the location of the cell, need to overcome obstacles, or cover a longer distance. Common types of such tools include a Yagi-Uda antenna and a panel antenna. They are often employed as external antennas for 4G devices.
- Panel antennas offer a good balance between coverage and directions. They have a wider beam width than Yagi-Uda antennas but still focus the signal in a particular direction, which makes them ideal for indoor coverage in homes and offices.
- Weatherproof antennas and ingress protection (IP) rating. For outdoor installations, choose a weatherproof antenna with an appropriate IP rating. Such solutions can withstand harsh weather conditions, preempting corrosion resistance, which is especially valuable in marine applications.
What antenna specifications to consider?
Pay close attention to these specifications while picking the right antenna:
- Frequency range (4G LTE bands). Ensure the antenna supports the frequency range used by your mobile network operator (MNO) for 4G LTE bands. Different carriers use different frequencies, so check your carrier’s specifications first.
- Antenna dain (dB) measures the antenna’s finesse to focus the signal in a given direction. Higher gain means a stronger signal, but it also narrows the coverage area down.
- Impedance. Antennas typically have an impedance of 50 ohms, so make sure your antenna, cables, and amplifier all have matching impedance for consistent performance.
- Voltage Standing Wave Ratio (VSWR). VSWR shows how well the antenna matches the amplifier and cables. A lower VSWR is better, but the ideal option is below 2:1. High VSWR, as a rule, indicates signal reflection and loss.
- Polarization is the orientation of the electromagnetic field emitted by the antenna. Vertical polarization is the most common for cellular technology.
How to mount your antenna in the right way?
The way you mount your antenna for 4G booster is key for its performance and longevity:
- Pole mount antennas
Ideal for outdoor installation, offering secure mounting. - Wall mount antennas
Suitable for mounting antennas on walls, providing a directed signal. - Magnetic mount antennas
Offer portability and ease of installation, commonly used for installation in vehicles. - Suction cup mount antennas
Similar to magnetic mounts but use suction for attachment. - Ceiling mount antennas
Designed for indoor use, delivering full coverage.
Ways to minimize signal losses with cables and connectors
The antenna, cables, and connectors are critical components of the 4G repeater:
- Keep the cable length as short as possible to minimize signal losses.
- Pick the appropriate SMA connector based on your amplifier and antenna requirements. N-type connectors are often employed for outdoor use cases due to their weather resistance.
Installation tips for the best performance
- Antenna positioning
Experiment with different antenna locations to find the best signal strength. - Antenna alignment
For directional antennas, carefully align the aerial towards the cell tower. Use signal strength meters or apps to optimize antenna alignment. - Line of sight (LOS)
Ideally, you should have a clear LOS between the antenna and the cell tower. Obstructions like trees and buildings can weaken the signal. - Ground plane
Some antennas require a ground plane for good performance. Peruse the antenna’s documentation for specific requirements.
Troubleshooting common issues with your antenna
- Poor signal strength
Check the antenna connection, antenna alignment, and cable length. - Interference mitigation
Identify and mitigate sources of interference that may be affecting the signal. - High VSWR
Check the antenna, cables, and connectors for damage or bad connections. - Compliance and regulatory standards
Ensure that your 4G signal amplifier and antenna comply with all applicable regulatory standards, including FCC regulations.
Conclusion
The correct antenna for the 4G booster is a revolutionary tool to redefined signal strength, so you and other users could enjoy faster and more reliable wireless connections. Just remember to always test and optimize the antenna alignment for the best possible results. And, for first-rate repeaters, lean on MyAmplifiers’ support!
