Fast Facts About This Product:

  • This repeater kit is best for: Users looking for a powerful option to boost the signal to one phone or hotspot that doesn't have an antenna port.
  • All-in-One Kit? YES
  • Compatibility: 800mhz/1900mhz networks, which are used by most 2G (voice) and 3G networks in the USA, including:
    • Verizon 2G/3G
    • Sprint 2G/3G
    • AT&T 2G/3G and HSPA+ (which shows up on your device as "4G" - NOT LTE)

IMPORTANT SIGNAL INFORMATION: If you're purchasing an amplifier for use at one specific location, we strongly recommend doing a site survey first to determine whether the amplifier will help you and to give you an idea of what kind of results you can expect from it.

If your signal is extremely poor (-108db or worse), an amplifier may not be effective - there must be some usable signal available for the amplifier to boost. Conversely, if the signal is too STRONG at your location (-50db or better), the amplifier may shut down to avoid interference with the tower.

The SignalBoost Cell Phone Signal Booster is the perfect choice for the user looking to improve cellular signals for a single cell phone or hotspot on the road. Virtually any phone or hotspot can fit in the included cradle to benefit from the signal boost.

How it works: The magnetic mount antenna picks up the cellular signal and sends it through the cable to the amplifier. The signal is then boosted and pushed out through the cable to the cradle; the phone or device sitting in the cradle the benefits from the boosted signal.

Installation notes:

  • The magnetic mount antenna MUST be connected to something magnetic or it will not work! If you're using the SignalBoost in a car/truck, you can simply stick it on the roof of the vehicle. For home use, we recommend buying the indoor accessory kit (sold separately), which includes a window mount that provides a magnetic base for the antenna.
  • Your phone or hotspot must be in the cradle to benefit from the signal boost.

The SIGNALBOOST combination works pretty much as promised. It gives us one more bar on the MiFi, which is often the difference between having a working signal or not. Times when we are not able to access the internet are now few. Well worth the investment for us. Alden H.

this is a perfect product for road warriors. I am in Estes Park Colorado tonight with 'no service' on my iPhone, but in the cradle it is 4 of 5 bars. I have similar success in remote areas of Nebraska(Alltel area) and Arkansas, and to/from these areas from my home in Illinois. Also, I use the same cradle to amplify my Verizon mifi and my ATT iPhone simultaneously....for weeks on end. I have purchased 3 units from 3gstore...for my truck, my camper, and for my father. I am constantly recommending this product!
