For our Canadian customers, the Wilson 8* series will soon run out of stock. Before being replaced by the Wilson 46* series, these products were unregulated by the FCC and IC, therefore, are more powerful than today's regulated boosters.

These legacy boosters are legal and grandfathered into program, and are in very limited supply.

Wilson 801240 MobilePro Amplifier Only is an ingenious wireless booster with +45dB gain designed for both mobile and indoor use. This slim super-portable device can be easily moved from vehicle to vehicle and also your home, office or hotel room.  Its unique design actually incorporates an interior antenna right into the amplifier so you only need to plug it in and add an outside antenna.  This Dual-Band amplifier features a respectable 45 dB of gain and 1-watt of output power.

You can expect a coverage range of 2-8 feet from the unit, depending on outside signal, making this an ideal choice for vehicles, as well as desktop or small rooms, particularly when you need amplification for a laptop of PC data card.  In addition to A/C and D/C power options, this amplifier can also be powered via your computer's USB port.  The 801240 does not include the outside antenna so users can pick one to best suit their needs.  We also carry two hot-selling kits with this amplifier, the 801241 (with a 12-inch outside antenna), and the 801242 (with a 4-inch outside antenna).


  • In-Vehicle signal booster designed for use in a car, truck, RV or boat. It can also be used indoors in a single room or desktop environment, particularly dorm rooms. Great for Laptops and personal computers.  Additional accessories required

MobilePro installation is very user-friendly and shouldnÌ´Ì_ÌÎ̴̝åÈt take more than 30 minutes. MobilePro amplifier systems have two separate components which need to be installed and connected: the amplifier unit and the exterior antenna. The amplifier unit includes both the amplifier and the interior wireless antenna in a single, compact housing.

First, install the adhesive mount in the desired vertical position of your dashboard (not on air bag cover). Allow 24 hours for the mountÌ´Ì_ÌÎ̴̝åÈs 3M adhesive to set before attaching the amplifier onto the mount. The included 5V car cigarette lighter power supply with a 3-foot USB/USB-mini cable will be used to power the amplifier. Additional 5V AC wall power supplies and 5V DC hardwire vehicle kits are available.

Second, install the magnet-mount exterior antenna (or optional trucker/marine antenna) in the desirable position in the center of your car roof or trunk (at least 12 inches away from other antennas and 6 inches away from windows or sunroof). Adequate separation between exterior antenna and amplifier antenna is needed for oscillation-free operation. The strong rare-earth magnet will securely hold the antenna in place. The antenna cable is thin enough to feed under the door rubber seal and through the door frame.

Finally, connect the exterior antenna to the amplifier and power the amplifier unit to turn the system on. Once connected and powered, your system will boost any compatible phone/network. A green light on the front of the amplifier indicates power on and optimal operation. Red light indicates that an automatic shutdown has taken place. This is either due to the exterior antenna and amplifier cradle being too close, or being too close to a cellular tower.

MobilePro systems are wireless amplifiers which will cover the inside of most passenger cars with signal being stronger closer to the amplifier (minimum 6-inch separation required). All vehicle occupants with compatible phone/networks will be covered and may use their phones in the regular way for all calling, texting, and browsing. Under ideal conditions, properly installed MobilePro systems will cover the inside of any passenger car or small truck.

MobilePro kits come with home/office accessories allowing easy desktop installation and vehicle-to-building mobility. The amplifier-only option does not include an exterior antenna.

  1. Amazing Product ratings and reviews

    Posted by Raymond Gragg on 22nd Feb 2013

    After installing the Mobile Pro, my signal went from two bars to five bars. The install was easy and took less than half an hour. It's not cheap, but well worth the money.
