Best Smoothtalker Cell Phone Boosters for Home

Smoothtalker Stealth cell phone signal boosters are designed to bring signal into your home, whether you live in the city or the country. Your amount of inside signal will depend on how strong your outside signal is. Boosters can only work if there is at least one bar of ambient cell signal. That being said, the stronger the booster, the further away from the nearest tower you can be.

Smoothtalker boosters can automatically adjust their gain via STEALTHTECH®. This gives a more reliable signal by eliminating feedback loop. A feedback loop or oscillation is where signal bounces between two points. These could be the internal and external antenna if they are too close or from the nearest tower. Signal overload from too many towers can also cause a feedback loop. STEALTHTECH® allows the signal booster to reduce signal power as soon as it detects oscillation, making sure your signal stays strong and reliable. When this happens, the booster will show a flashing green light on the indicator panel.

Both the Z and X series of boosters in the Smoothtalker range have several options for antennas, gain, and ohmage. You can choose the perfect mix for your situation, ensuring that you get the best signal.

Smoothtalker Z6 Series

The Smoothtalker Home Stealth Z6 series is the brand’s flagship booster range. There are three boosters within the range, namely the Z660, the Z665, and the Z670. Get up to +75 dB of gain across up to 10,000 square feet. Each of these has been designed for a different size space, with total gain dependent on outside signal. You also get a choice of three antennas:

  • Wide Directional: 180-degree beamwidth. Great for good signal areas with lots of towers like within cities.
  • Directional: 170-degree beamwidth. Works well areas that have multiple towers
  • Beam Directional: Strongest option for more rural areas

The Z6 series comes in a choice of 50 or 75 ohms. 75-ohm is classed as better for consumers as the cable is thinner and easier to fit through walls and windows. That being said, 50-ohm cables have less loss over distances. In a normal consumer home, there isn’t really going to be a huge difference between 50 and 75 ohms, so we recommend that you choose the 75 option.

Best for smaller, urban areas with strong outside signal: Home Stealth Z660

  • Max gain +60 dB
  • Boost 4G and LTE
  • All phones & cellular devices, all Canadian carriers
  • Complete kit

The Z660 gives you a max gain of +60 dB, depending on outside signal. It’s perfect for small homes or offices in the city where there are many towers. Cover up to 233 square meters with good, stable signal.

Choose from three outside antennas:

  • Wide Directional: Choose this if you live in a built-up area, with strong outside signal and many towers.
  • Directional: Thinner beam than the wide directional. Choose this if you need to focus on a specific area of towers and have weaker outside signal.
  • Beam Directional: Strongest option with most focussed beam. Choose this if you need to zoom in on a particular tower if you live far away from them. This will increase your Z660s gain and coverage area if your signal is poor.


Best for slightly larger urban homes, or smaller suburban ones with good outside signal: Home Stealth Z665

  • Max gain +65 dB
  • Boost 4G and LTE
  • All phones & cellular devices, all Canadian carriers
  • Complete kit

The Z665 gives you a max gain of +65 dB, depending on outside signal. Choose this option if you have a bigger space to cover or a smaller space with a weaker outside signal. Perfect for larger urban homes, or smaller suburban ones. Cover up to 465 square meters with good, stable signal.

Choose from three outside antennas:

  • Wide Directional: Choose this if you live in a built-up area, with strong outside signal and many towers.
  • Directional: Thinner beam than the wide directional. Choose this if you need to focus on a specific area of towers and have weaker outside signal.
  • Beam Directional: Strongest option with most focussed beam. Choose this if you need to zoom in on a particular tower if you live far away from them. This is the best option to get the maximum gain on your Z665.


Best for slightly larger urban homes, or smaller suburban ones with good outside signal: Home Stealth Z670

  • Max gain +70 dB
  • Boost 4G and LTE
  • All phones & cellular devices, all Canadian carriers
  • Complete kit

The Z670 gives you a max gain of +70 dB, depending on outside signal. This is the best option for large urban homes or medium-sized suburban ones. It covers up to 930 square meters with a strong outside signal but will cover a smaller area if the signal is weaker.

Choose from three outside antennas:

  • Wide Directional: Choose this if you live in a built-up area, with strong outside signal and many towers.
  • Directional: Thinner beam than the wide directional. Choose this if you need to focus on a specific area of towers and have weaker outside signal or live in a suburban area.
  • Beam Directional: Strongest option with most focused beam. Choose this if you need to zoom in on a particular tower if you live in a more rural area. This option will get you the best maximum gain to cover the largest area possible.


Smoothtalker X6 Extreme Series

This is Smoothtalker’s most powerful signal booster and is best for rural or isolated areas. It can also be used for commercial installations in small office buildings. Like the Z series, there are multiple options in the range, namely the X660, the X665, and the X670. All three come standard with STEALTHTECH®. Maximum gain ranges from +60 dB to +75 dB, depending on the outside signal.

As with the Z Series, you can choose from one of three outdoor antennas.

  • Wide Directional: 180-degree beamwidth. Best for areas with a good outside signal like cities.
  • Directional: 170-degree beamwidth. Best for areas with slightly weaker signal where you need to focus more on an area of towers.
  • Beam Directional: Best for weak outside signal areas where you need to focus on a particular tower.

Stealth X660 Extreme Power

  • Max gain +60 dB
  • Boost 4G and LTE
  • All phones & cellular devices, all Canadian carriers
  • Complete kit

The Smoothtalker Stealth X660 Extreme Power signal booster is designed for homes or commercial areas with large coverage spaces. Get up to +60 dB depending on outside signal. The better the signal, the bigger the area you will be able to cover. It is also great for rural areas with weak outside signal and smaller coverage spaces. Boost stronger, more stable signal across up to 930 square meters under perfect conditions.

The X660 comes with a choice of three outside antennas:

  • Wide Directional: Choose this if you are urban based and want to draw in signal from numerous surrounding towers.
  • Directional: Thinner beam than the wide directional. Choose this if you need to focus on a specific area of towers and have weaker outside signal or are based outside of the city.
  • Beam Directional: Strongest option with most focussed beam. Choose this if you need to zoom in on a particular tower if you live in a more rural area. This option will get you the best maximum gain to cover the largest area possible.


Stealth X665 Extreme Power

  • Max gain +65 dB
  • Boost 4G and LTE

This signal booster is great for more rural buildings that have weaker outside signal. Cover up to 744 square meters with strong outside signal, or a smaller area if the signal is weaker.

Pick one of three outside antenna options:

  • Wide Directional: Choose this if you are in an area with several cell towers.
  • Directional: Thinner beam than the wide directional. Choose this if you are slightly further away from towers and need an extra boost to your available max gain. This will focus on an area of towers like a flashlight.
  • Beam Directional: Strongest option with most focussed beam. Choose this if you are rural or isolated and need the best signal from a faraway tower.


Stealth X670 Extreme Power

  • Max gain +70 dB
  • Boost 4G and LTE

  • Complete kit

The Stealth X670 Extreme Power signal booster is Smoothtalker’s most powerful consumer and commercial booster. It is designed for large spaces or very rural areas with weak signal. Get up to +70 dB under best conditions. Even if you have only one bar of signal outside this booster will get you more bars inside. If you have strong outside signal you can cover up to a massive 1673 square meters. This is the best choice for large commercial areas like warehouses, retail stores, or office buildings.

Pair your X670 with one of three antenna options

  • Wide Directional: Choose this if you are in the city and have lots of nearby cell towers
  • Directional: Thinner beam than the wide directional. Choose this if you are slightly further away from towers and need an extra boost to your available max gain. This will focus on an area of towers like a flashlight.
  • Beam Directional: Strongest option with most focussed beam. Choose this if you are rural or isolated and need the best signal from a faraway tower.


Best Smoothtalker Cell Phone Boosters for Vehicles
