Fast Facts About This Product:

  • This repeater kit is best for: mobile users who need to boost the signal wirelessly to up to three devices in a small location and need something portable (for example, traveling sales reps who frequently use rental cars in rural territory). The MobilePro requires no permanent installation and can easily be transported, but it is not the most powerful option and the devices must be very close to the amp to benefit from the boosted signal.
  • Coverage area*: 1-5'
  • 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)
    • T-Mobile and Cricket voice only
    • Does NOT work with LTE for any carrier or AWS (T-Mobile 3G/4G)

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.

Improve cell phone and data card performance on the road, in your home or at the office - anywhere you need a stronger cellular signal. Easy to set up and no installation required - perfect for taking with you wherever you go!

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 sent out through the built-in rebroadcasting antenna. All of your modems/phones within range of the amplifier can benefit from the boosted signal wirelessly.

*Many factors will influence the actual coverage area you will see from a repeater, including layout/floorplan, construction, and original un-amplified signal strength. Depending on your situation, you may see more or less coverage than the estimates listed here. It is not possible to guarantee coverage area.

This kit is the SAME as the Wilson 801242, but includes the taller antenna (the 801242 includes a shorter magnetic mount antenna)

Installation notes:

  • Your phones/modems must be VERY close to the amplifier (typically 1-5') to benefit from the signal boost.
  • The magnetic mount antenna MUST be connected to something magnetic or it will not work! A suction cup window mount, which provides a magnetic base for the antenna, is included in this package.

I'am in an area where I have 2 big electrical power lines blocking my signal (105 KVA) I used to get 2 sometimes 3 bars on my Verizon access manager. My signal now stayes peged at 4 bars and my speeds have gone from around 50kb/sec. to 150kb/sec. and higher. I think I can even improve this if I move my antena just a little. Well worth the investment.

This thing really works! I was skeptical at first when ordering. I have a Sprint MiFi 2200 that was getting 1-2 bars and -100+dBm. After installing this SignalBoost I get 5 bars and -72dBm. Hard to believe how well this works! Well worth the money and easy to install. Thanks for a reasonably priced amplifier that really works! AAA+

I was unsure at first but at my job site my panasonic cf30 with the embedded sprint 5725 card i could only get -105db which toggled my service between evdo and 1x. very frustrated until i received this wilson amp, WOW i went from -105db 1-2 bars to a WHOPPING -63db full 8 bars. I set the included antenna on the window with the suction cup mount and put the amp about a foot from my laptop unreal i would have never thought this would have worked this well. Buy IT !
