Car Cellular Phone Signal Booster & Repeater Antenna 5G, 4G LTE for Verizon At&t Sprint T-Mobile Phones by Cellet

1.The antenna is to be placed outside of the car window.
2. The square repeater is to be placed inside of the car window (Make sure the square repeater is aligned right below the antenna).
3. This device is to be used in automobiles only, if you want to use this at your home PLEASE READ DESCRIPTION BELOW.
4. For best signal improvement, the booster must be installed at least 3 feet away from your phone or installation location. This spacing allows the passive antenna to capture and redirect existing tower signal effectively.
DISCLAIMER: Passive Booster (Non-Amplified): Does not create or amplify signal — only redirects existing signal from nearby towers. Performance Depends on Environment: Car construction, terrain, and carrier coverage impact results. Not for zero-signal areas: A minimum existing signal is required for the passive booster to redirect.

Your Guide to Boosting Cell Signal: Buying a Cell Phone Signal Amplifier

Are dropped calls and slow internet driving you crazy? A cell phone signal amplifier, also called a booster, can fix that. This guide helps you choose the right one for your home or office. Boosters catch weak outside signals, make them stronger, and send them inside. You get better calls and faster data.

Key Features to Look For

When shopping, look closely at what the amplifier kit includes and what it can do.

Signal Strength Improvement

Gain (dB): This number shows how much the amplifier boosts the signal. Higher numbers mean a stronger boost. Look for at least 50 dB for small areas or 60-70 dB for larger homes.
Coverage Area: Check how many square feet the booster covers. Small kits cover a room or small apartment. Larger kits cover whole houses or multiple floors.

Compatibility and Bands

Carrier Support: Make sure the booster works with your cell carrier (like Verizon, AT&T, T-Mobile). Most good boosters work with all major carriers.
Frequency Bands: Cell signals use different radio frequencies (bands). A good booster supports the bands used for voice and data in your area. Look for support for common bands like 700 MHz, 1900 MHz, and 2100 MHz.

Installation and Design

Kit Components: A full kit needs three main parts: an outdoor antenna, an amplifier unit, and an indoor antenna. Check that all parts are included.
Power Source: Ensure the amplifier plugs easily into a standard wall outlet.

Important Materials and Build Quality

The materials used affect how long your booster lasts, especially the outdoor antenna.

Antenna Durability

The **outdoor antenna** must handle weather. Look for antennas made of strong, weatherproof plastic or aluminum. These materials resist rain, snow, and sun damage.
The **cables** connecting the parts must be high quality. Thick, shielded cables reduce signal loss as the signal travels from the antenna to the amplifier.

Heat Management

The amplifier unit itself creates heat. Good quality units have built-in heat sinks or vents. This design helps the device stay cool, which keeps the performance high and prevents early breakdown.

Factors That Improve or Reduce Quality

What makes a booster work great, and what makes it fail?

Improving Quality

Antenna Placement: Placing the outdoor antenna as high up as possible and pointing it toward the nearest cell tower greatly improves the incoming signal quality.
Separation Distance: You must keep the indoor and outdoor antennas far apart. If they are too close, they can cause feedback (like a microphone squeal), which lowers performance.

Reducing Quality

**Building Materials:** Thick materials like concrete, metal roofing, or energy-efficient windows block signals. If your walls are very thick, you might need a more powerful booster or professionally installed antennas.
**Poor Installation:** If the outdoor antenna is hidden inside or pointed the wrong way, the booster will only amplify a weak, noisy signal.

User Experience and Use Cases

How easy is the booster to use, and where do people need them most?

Ease of Use

Most modern boosters are plug-and-play. You connect the antennas, plug in the power, and the device automatically starts working. Some have indicator lights to show if the signal is strong enough. Simple setup means less frustration for the user.

Common Use Cases

Rural Homes: People living far from cell towers often need boosters to get any reliable connection.
Basements and Offices: These areas often have poor signal because they are underground or surrounded by many walls. A booster placed near a window can bring signal down to the lowest level.
RVs and Boats: Mobile users need specialized antennas to capture weak signals while moving or parked far from urban areas.

10 Frequently Asked Questions (FAQ) About Cell Phone Signal Amplifiers

Q: Will a signal booster work if I have zero bars outside?

A: It needs *some* usable outside signal to work. If there is absolutely no signal (zero bars, no connection), the booster has nothing to amplify. It works best when you have at least one weak bar outside.

Q: Is it legal to use a cell phone signal booster?

A: Yes, they are legal in the US and Canada, but they must be certified by the FCC (in the US). Uncertified boosters can cause interference with the cell network.

Q: Do I need a separate booster for 4G/5G data and voice calls?

A: No. Most modern, quality boosters cover all the necessary frequency bands used for both voice (calls) and data (internet) across all major carriers.

Q: How do I find the best spot for the outdoor antenna?

A: You need to point the outdoor antenna toward the nearest cell tower. Check your carrier’s website or use a signal-finding app to locate the tower direction.

Q: Can one booster cover my entire two-story house?

A: It depends on the booster’s power rating (gain) and the construction of your house. Larger, higher-gain systems are designed for multi-story homes, but you might need multiple indoor antennas.

Q: Does the booster slow down my internet speed?

A: No. If the outside signal is weak, the speed will be slow. The booster improves the speed *because* it provides a stronger connection, not by slowing it down.

Q: What is “oscillation” or “feedback”?

A: Oscillation happens when the indoor antenna sends the boosted signal back to the outdoor antenna. This creates a loop, causing the amplifier to shut down or perform poorly. Keep the antennas separated!

Q: Do I need a special subscription for a signal booster?

A: No. Once you buy the hardware, there are no monthly fees to use the booster itself.

Q: How long does the installation usually take?

A: For a standard home kit, most people finish installation in one to three hours, depending on how easy it is to run the cables to the roof or attic.

Q: Will the amplifier boost the signal for multiple cell phones at once?

A: Yes. Once the signal is boosted inside, it is available to every cell phone, tablet, or mobile hotspot inside the coverage area, regardless of the carrier.
