The 811201 only includes the DC (vehicle) power supply. If you plan to use this amp indoors, you'll need to add the AC power supply here.
Add the AC Power Supply (optional) - details
The yagi antenna REQUIRES line of sight to the tower (it will not work if you don't know where the tower is or if there are obstructions between you and the tower). The panel antenna is also a directional antenna and must be aimed towards the tower, but it does NOT require line of sight. If you are not sure where the cell tower is, you should choose one of the omnidirectional antennas. If you already have an antenna you plan to use, you can select the "I already have an antenna" option.
Select Antenna - details
The Magnetic Mount Antenna, Indoor/Portable Antenna, Omni RV Antenna, and Omni Trucker Antenna all INCLUDE cabling. The other antennas do NOT include cabling and you must select a cable here to connect the antenna to the amplifier (for the ultra-low-loss cabling, we bundle the connector you'll need to connect the cable to your amplifier). If you already have a compatible cable you plan to use or if you selected one of the antennas that includes cabling, you may select the "I already have a cable" option.

Do a site survey before buying this amplifier! If you're purchasing this to use in just one location, we strongly recommend doing a site survey first to determine whether the amplifier will help your signal and performance and to give you an idea of what kind of results you can expect from it. Start here: Will an Antenna/Amplifier Help Me?

If your signal is extremely poor (-108db or worse), an amplifier may not help you. There must be some usable signal available for the amplifier to boost for it to be effective.

How it works: The outside antenna (sold separately) picks up the cellular signal and sends it to the amplifier. The signal is then boosted and sent out through the patch antenna, which sticks to the back of your phone or hotspot.

This amplifier is NOT the same as Wilson's 3-Watt Direct Connect amplifier (811201). If you are looking for the Direct Connect amplifier (which connects directly to a phone/modem's antenna port via an adapter cable), click here

Installation diagram:

not to scale. representative graphic only. exterior antenna is NOT included.

Installation notes:

  • The patch antenna must be stuck directly onto the back of your phone or hotspot. Your device will not benefit from the boosted signal unless the antenna is in contact with the device.
  • The patch antenna should be as close to the device's internal antenna as possible. You may need to experiment with placing the antenna in different locations on the phone/hotspot to find the optimum location.
  • For more details, you can download the complete installation guide (PDF)


  • Can be used with virtually any 2G/3G phone or hotspot

I love this gear! Not only does it work, but because of their adaptive power control nothing is overloaded at cell towers. I will always shop here for this gear 3 days to Australia... not bad!
