They amplify a weak or shadowed signal in mobile, marine, M2M and in-building applications. When using a Wilson Electronics Signal Booster in conjunction with Wilson Electronics antennas, the Outside Antenna will collect the cell tower signal and send it through the cable to the Signal Booster. The signal is then amplified and re-transmitted through the Inside Antenna into the room. Cell phones and cellular data cards in that area then communicate with the improved signal. When a cell phone or cellular device transmits, the signal is received by the Inside Antenna, amplified by the Signal Booster and broadcasted back to the cell tower through the Outside Antenna.Inside this PackageSignal BoosterAC/DC Power SupplyTo purchase, call Wilson Electronics Sales Department at: 800-204-4104Outdoor Antenna Options Indoor Antenna Options & Accessories1.

Run the Inside Antenna cable to the Signal Booster and attach it to the connector labeled “Inside Antenna” on the Signal Booster (see page 7 for more information on running cable). Lightning Surge Protection is recommended for all in-building installations (see page 6).Select a location for the Inside Antenna, preferably in the 4. center of where the signal needs to be amplified. A minimum separation distance (combined vertical/horizontal) of 20 feet is necessary for operation (see page 8). If the inside coverage is not sufficient you may need as much as 50 feet of separation. See installation diagram on pages 3 & 4. Before powering up the Signal Booster, verify that both the 5. Outside Antenna and the Inside Antenna are connected and check that all connections are tight. Note: Be careful when plugging the connectors in so as not to bend the center pins on the connectors.The Signal Booster has been packaged with the gain control 6. knobs adjusted to the highest gain position.

Hours: 7 am to 6 pm MST.6Reasons for Weak Cellular SignalsAnyone who uses a cell phone or cellular data card knows the frustration of not being able to connect to or maintain a strong cellular signal. When this occurs, it is generally due to one of two reasons:Location of the Nearest Cell Tower – Cell towers are situated 1. to provide broad coverage; however, there are many areas in which signal strength may be reduced by topographic features or by local government restrictions on the height or placement of the towers themselves. Rural areas generally have fewer cell towers than urban regions.Natural and Man-Made Obstructions – Signal strength can 2. also be negatively affected by trees, hills, buildings, weather, and other obstructions. You may be relatively close to a cell tower but still unable to make a call. This often occurs in homes, offices and other buildings in which stucco, concrete or metal walls may block the signal.The Signal Booster works with two antennas. The Inside Antenna communicates with your cellular device and the Outside Antenna communicates with the cell tower. The Outside Antenna receives the cell tower signal and sends it through the cable to the Signal Booster, where it is amplified and re-transmitted much stronger through the Inside Antenna into the room. When the Inside Antenna picks up a signal from your cellular device, the Signal Booster amplifies that signal and transmits it through the cable to the Outside Antenna and back to the cell tower. (Note: The Signal Booster will only operate if there is an adequate signal to amplify.)

The mounting bracket, included with Outside Antenna, is adjustable and will accommodate pipe diameters from 1.25” to 2” (pipe sold separately Part# 901117). Mount the antenna so that there is at least 3 feet of clearance in all directions around it. Position the antenna so that it has an unobstructed line of sight to the cell tower’s strongest signal. Make sure the Outside Antenna is not pointing across your own roof or at the Inside Antenna as this will cause the oscillation protection circuitry to shut down the Signal Booster. Warning Lightning protection is recommended for all installations (sold separately) (Part #859902). Take extreme care to ensure that neither you nor the antenna comes near any electric power lines.Install the Lightning Surge Protector (LSP) close to the Signal Booster. Attach the cable from the Outside Antenna to the surge protector, using a short length of low loss cable; attach one end to the LSP and the other to the Outside Antenna connector on the Signal Booster. Attach a ground wire (not included) to the LSP. LSP may be purchased at www.WilsonElectronics.com or 800-204-4104.To the Outside AntennaGround Wire(not included)Lightning Surge ProtectorSignal Booster

Hours: 7 am to 6 pm MST.8Mounting Tips for Running Outside Antenna CableIf you are mounting the Outside Antenna on the roof of your building, we have found that it is easiest to run your cable underneath the down side of your roof’s flashing. If you have satellite TV service installed at your home or office, you may be able to follow the same route as the satellite TV cables that are already running from outside of your building to the inside. After routing the cable, we recommend sealing any areas where the cable passes into the building with silicone, cable bushings or other waterproof sealant to keep your installation from leaking. If you are mounting the Outside Antenna to the outside wall of your home or building, the simplest way is to run the cable on the outside of the wall and attach it to the exterior of your home or office. Then drill a hole through the wall where you want the cable to appear on the inside of the building. Before drilling, make sure that there are no electrical outlets, sewer or water pipes, or electrical wiring in the wall that you are about to drill through as this could potentially harm you or damage the building. After drilling the required hole, run the cable through and seal it with silicone, cable bushings or other waterproof sealant to Selecting a Direction for the Outside AntennaSelect a location on the roof of the building to install the Outside Antenna. Use a cell phone in test mode to find the strongest signal from the cell tower. See below for more information. To get the strongest signal possible, it is very important to set up your Outside Antenna properly. The Inside and the Outside Antenna must be mounted in such a way that they are able to pick up the best possible cell signal on the outside of the building and provide the best possible signal on the inside of the building. Mount the Outside Antenna as high as possible facing the cell tower in an area with the best possible signal coverage. Note: Never point the front of a directional antenna toward the Inside Antenna. See Figures 1 & 2 on page 12.

In some instances, it may be possible to run the cable up into the fascia of the attic overhang. In this circumstance, the cable will be accessible in the attic for further routing.Installing the Inside AntennaFind the desired location for the Inside Antenna (Panel Antenna option shown). Verify that the Inside Antenna and the Outside Antenna have the necessary separation (Minimum of 20 vertical/horizontal feet if installed with Signal Booster set at a lower gain, for maximum gain you may need as much as 50 feet of separation). For optimum results the antenna should be mounted at least 6 feet off the ground.Ceiling RaftersInside AntennaIn some cases, multiple Inside Antennas may be required, for instance if you have multiple rooms with poor signal. A signal may be split by using a splitter (sold separately). If using more than one Inside Antenna, a separation of at least 20 feet is necessary between Inside Antennas. See configuration on pages 3 & 4. Warning: An Inside Antenna must have a separation distance from all persons that is at least 8 inches.Splitter Options:3-way (859980)4-way (859981)2-way(859957) (sold separately)Optional Panel Inside Antenna (sold separately)

Hours: 7 am to 6 pm MST.10Installing a Wilson Electronics Signal BoosterSelect a location to install the Signal Booster that is away from excessive heat, direct sunlight, moisture and that has proper ventilation. Do not place the Signal Booster in an air-tight enclosure. Recommended installation locations for in-building Signal Boosters are near a power outlet and in a closet, or on a shelf.Note: It is important to have adequate air ventilation. Maintain at least 6 inches of clearance from surrounding objects. Run the Outside Antenna cable to the Signal Booster and attach it to the connector labeled “Outside Antenna” on the Signal Booster. Run the Inside Antenna cable to the Signal Booster and attach it to the connector labeled “Inside Antenna” on the Signal Booster. Note: For distances of 20 feet or more, use Wilson low loss cable to prevent significant signal loss.Note: Be careful when plugging the connector in so as not to damage the center pins on the connectors.

Hours: 7 am to 6 pm MST.12Finding the Strongest SignalWhen installing your Signal Booster’s Outside Antenna, aiming it towards the best signal source from you service provider is important. After you have completed the install, the best way of getting the strongest signal is to have one person on the roof to rotate the Outside Antenna, which is connected to the Signal Booster. Turning the Outside Antenna about 45 degrees at a time, while the second person is watching the signal strength on the phone inside the building. This allows you to read the signal strength from the cell tower. It is preferable to have the phone in the test mode so the actual signal strength can be read, as bars are not the most accurate. Go to www.WilsonElectronics.com for help in finding the test mode for your phone. Always make sure the person inside the building gives the signal time to arrive and register on the phone. (Between 10-30 seconds for phone to reset to the signal reading). Signal readings usually appear as a negative number (for example, -86). The closer you get to zero the stronger the signal.

Hours: 7 am to 6 pm MST.14During installation mode the Signal Booster is resetting itself very quickly to aid the installer. The Signal Booster is equipped with one indicator light for the 700 MHz band and one for the power. For the first 15 minutes that the Signal Booster is plugged in, it is programed for a test and alignment period. 1. BLINKING GREENIf the Signal Booster 700 MHz light is blinking green, the Signal Booster is operating properly. If you are happy with the coverage area in your building, then you are done. Blinking will stop after the 15 minute installation period.2. BLINKING ORANGEIf the 700 MHz light on the Signal Booster is blinking orange, the Signal Booster is experiencing receiver (cell tower) overload. The Signal Booster has protection shut off circuits to prevent the disruption of cell towers. If the light is blinking orange, this indicates that gain should be reduced due to close proximity to a cell tower. First, turn down the uplink (UL) gain control until you get a blinking green light. Do not adjust the downlink (DL) knob at this time. The Signal Booster is now working with reduced gain on the uplink. If the gain is not adequate for good coverage, you will need to turn the UL gain to maximum and then rotate the Outside Antenna until the light turns to blinking green, waiting 5 seconds between each adjustment for the Signal Booster to Understanding the Signal Booster Lights and TroubleshootingNote: If after the initial 15 minutes you are not done with the installation, the Signal Booster can be reset and enter installation mode again by disconnecting and reconnecting the power supply from the Signal Booster.For the first 15 minutes the 700 MHz light will do one of the following 4 things:

If you do not get a green light, turn the UL gain down 5 dB and rotate the Outside Antenna. Continue to adjust the UL gain and the Outside Antenna position until the light turns blinking green. If the UL gain was reduced and the light is green and you have good signal strength but are unable to place a call, it may be necessary to lower the DL gain control to the same setting as the UL. This is because some cell systems require a balanced gain between UL and DL for proper operation. Contact Wilson Electronics Technical Support Team for assistance: 866-294-1660.3. SOLID REDIf the 700 MHz light on the Signal Booster is solid red, this indicates that the Signal Booster has shut down to prevent an oscillation (feedback). First, make sure that all the connections are tight. Then reduce the DL and the UL gain of the Signal Booster in 5 dB increments by rotating the gain control counter-clockwise, waiting 5 seconds between each adjustment for the Signal Booster to reset. Continue this adjustment until the 700 MHz light turns blinking or solid green. When you are turning down the DL gain, you are reducing the inside coverage area. If the amount of coverage area is sufficient for your needs and the 700 MHz light is green, the installation is complete. If the coverage area is not large enough, it is necessary to increase the separation distance of the Inside and Outside Antennas by moving them horizontally and/or vertically farther apart. Then increase the DL and UL gains until the red light comes on, and then decrease the gains until the green or blinking green light appears. If after separating the antennas your coverage area is still too small, contact Wilson Electronics Technical Support Team for assistance: 866-294-1660.4. SOLID GREENThe 700 MHz indicator light on the Signal Booster will be a solid green after the first 15 minute installation period, if the unit is powered up and working properly.
