This item has been discontinued. For the updated version please look at the Wilson Mobile 3G +50dB Amplifier Kit - 460102

The Wilson 801212F Mobile 3G complete kit is by far the Top Selling mobile solution in the Wilson product line.  It is also the most powerful vehicle amplifier kit.  The heart of the kit is the 801201, a solid 3-Watt Dual-Band (850/1900 Mhz) mobile wireless amplifier.  Part of Wilson's SignalBoost HDMobile Wireless Professional Series, this robust amp packs 50 dB gain on the 850 Mhz Band range and 50 dB on the 1900. All North American carriers are supported (except Nextel/iDen, 4G, WiMax, and other signals not on the 850/1900 bands).  If you need extra signal boost in extremely weak signal areas, consider the field-tested 801212-B complete kit we put together.

The device is built to simultaneously support multiple users (on phones and data cards) wirelessly. The unit can be used in a car, truck, RV or boat, and is designed to improve your device's performance and signal strength for fewer dropped calls, clearer reception, and faster data rates. This package includes Wilson's new Low Profile inside-vehicle antenna, and the 301103 12-inch Magnet Mount Outside Antenna.

This little beauty features an impressive 5.12 dBi on the 850 band range and 6.12 dBi on the 1900 Mhz frequency.  A metal ground plane is required, but easily achieved once the antenna is placed on the roof of the vehicle.

UPDATED: As of February 2014, the manufacturer changed the connectors from FME to SMA. If you purchased your Wilson 801212 on and after this date, you will most likely need SMA cables. 


  • The 801212 In-Vehicle signal booster kit desgined for use in a car, pickup, truck, RV or boat. It can also be used indoors with the optional Home Accessory Kit.


  • Works with all Cellular and PCS Carriers

Mobile Wireless installation is user-friendly and shouldnÌ´Ì_ÌÎ̴̝åÈt take more than 45 minutes. Mobile Wireless amplifier systems have three separate components which need to be installed and connected: the amplifier unit, the exterior antenna, and the interior antenna.

First, install the metal amplifier unit on the floor under the passenger seat using the four mounting screw holes for secure attachment. The included 6V car cigarette lighter power supply with a 6-foot cable is used to power the amplifier. Additional 6V AC wall power supplies and 6V DC hardwire vehicle kits are available.

Second, install the included exterior antenna (or separate FME-type antenna) in the desirable position on the high, unobstructed point of your vehicle (with at least 12 inches away from other antennas and 6 inches away from windows or sunroof). Adequate separation between exterior antenna and interior antenna is needed for oscillation-free operation. Different exterior antennas will have different installation procedures (magnet-mount, glass-mount, NMO, trucker, marine).

Third, install the interior antenna on the side on front row seat or other inside location facing away from the exterior antenna and covering most of the interior area. The Low Profile Ì´Ì_ÌÎ̝ÌÎåHershey BarÌ´Ì_ÌÎÌÌ´å antenna has a velcro adhesive strap for easy mounting and removal. The kit including the wired Cradle Plus antenna will also include the Hershey Bar antenna for setup flexibility (only one antenna may be used at any time).

Finally, connect the exterior and interior 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 in its coverage area. A green light on the side of the amplifier indicates optimal operation. A 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.

Mobile Wireless systems are wireless (except the Cradle Plus option) and will cover the inside of most passenger cars with signal being stronger closer to the interior antenna (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 Mobile Wireless systems will cover the inside of any passenger car or small truck.

Optional home/office accessories are available to allow easy in-building installation and vehicle-to-building mobility. The amplifier-only option does not include an exterior antenna.

  1. Great lil amp ratings and reviews

    Posted by Chuck Payne, Northern Neck of Virginia on 27th Mar 2014

    This is actually the second one I have owned. But this one is for my wife's car. This thing really does will with providing just enough amplification to the signal when you're in a low coverage or "dead" area that you don't drop a call, especially in some of the hilly areas of Virginia.

  2. Worked as promised ratings and reviews

    Posted by West Texas Fence Man on 26th Feb 2014

    I travel throughout Texas, especially all of the western side. Had a friend that works in the oilfield reccommend this unit to me. Was out in an area that normally would not have signal. I had no problem getting it. Only down side, it does not support 4g LTE. But I still was able to have phone and text service . Was very impressed. Pleased with the purchase.

  5. Not so sure yet!! ratings and reviews

    Posted by Jason P- West Texas on 5th Nov 2013

    Got the unit a day before trip to far West Texas. Not many spots I have trouble in, but knew of one road I really wanted to see how the unit worked. The unit did increase the bars on my phone, but still could not call out or recieve calls. This was for a 25 mile stretch of road. Will be going out to the ranch for another test. Hope to have better results!

  6. If You Want Performance instead of Promises Buy This Right Now!! ratings and reviews

    Posted by Wes Surritt - Southern Ohio on 18th Oct 2013

    As a general contractor that travels seventeen state our firm has five of the cradle-type units in use (all delivering everything promised)and when I purchased a new vehicle I decided to opt for this unit and it delivers the superior performance we have come to expect from Wilson. If you can't make a call when this amplifier is in your vehicle you need to consider a sat phone. Keep up the good work Wilson.

    Posted by michael ferrick/northern WI, northern MN, to Canada on 29th Aug 2013

    I work from south of Superior to north of Duluth, MN to the Canadian border, with rarely reception anywhere, and I rely on my phone to receive my jobs. This makes my job possible, without it I wouldn't be able to work here!

    Posted by Fairbury,NE on 16th Aug 2013

    Live and work in Rural Nebraska and Kansas with many hours spent on the road. Service is patchy on a good day. This is the second Wilson booster I have owned in five years. Wore out the first one. It is a must have. Great product!
