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 transmitted back to the cell tower through the Outside Antenna.Inside this PackageSignal BoosterAC/DCPower Supply6V / 2.5ATo purchase, call Wilson Electronics Sales Department at: 800-204-4104Outdoor Antenna Options Indoor Antenna Options & Accessories1.

Contact Wilson Electronics Technical Support Team with any questions at 866-294-1660.Select a location to install the Signal Booster that is away from excessive 1. heat, direct sunlight, moisture and has proper ventilation. Do not place the Signal Booster in an air-tight enclosure. Select a location on the roof of the building to install the Outside Antenna. 2. Use a cell phone in test mode to find the strongest signal from the cell tower (see page 6). Visit www.WilsonElectronics.com to find test mode function for your particular cell phone.Run the Outside Antenna cable to the Signal Booster and attach it to 3. 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. For more information on running cable (see page 7). Lightning Surge Protection is recommended for all in-building installations (see page 6).Select a location for the Inside Antenna, preferably in the center of 4. where the signal needs to be amplified. A minimum separation distance of 20 vertical (within the null zone) or 50 horizontal feet is necessary for proper operation. If the inside coverage is not sufficient you may need to increase the separation distance even further (see installation diagram on pages 3 & 4). Before powering up the Signal Booster, verify that both the Outside 5. 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 (see page 9).The Signal Booster has been packaged with the gain control knobs 6. adjusted to the highest gain position. If one or both of the lights are not green, please refer to pages 10-12. Warning: Connecting the Signal Booster directly to a cell phone with use of an adapter will damage the cell phone and/or the Signal Booster.IMPORTANT NOTICE It is very important to power your Signal Booster using a •surge protected AC Power Strip with at least a 1000 Joule rating.Failure to do this will void your warranty in the • event of a power surge or lightning strike.

Hours: 7 am to 6 pm MST.6Cell TowerReasons 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 to 1. 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 also 2. 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 cell phone 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 antenna should be mounted as shown in the illustration above.The mounting bracket, included with antenna, is adjustable and will accommodate pipe diameters from 1.25” to 2” (pipe sold separately #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 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 (see Figures 1 & 2 on page 10).Outside Antenna Installation (#304411 shown) Drip hole on bottomAntenna

Warning: Lightning protection is recommended for all installations (sold separately #859902). Take extreme care to ensure that neither you nor the antenna comes near any electric power lines. 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 10.Installing Lightning Protection(sold separately)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. Ensure the LSP is properly grounded (ground wire not included). Visit www.WilsonElectronics.comor call 800-204-4104 to purchase.Finding the Strongest SignalWhen installing your Signal Booster’s Outside Antenna, aiming it towards the best signal source from you service provider is important. 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.

Hours: 7 am to 6 pm MST.8Signal readings usually appear as a negative number (for example, -86). The closer you get to zero the stronger the signal (see graph above). Mounting 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 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 cable bushings, silicone 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. 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). -50dB -60dB -70dB -80dB -90dB -100dB -110dBEXCELLENT GOOD POOR NOSIGNALSignal Strength GraphCell TowerCell SignalOutsideWide Band Antenna

A minimum separation distance of 20 vertical feet is necessary for operation. If the inside coverage is not sufficient you may need as much as 75 feet of horizontal separation. See installation diagram on pages 3 & 4.Ceiling RaftersCeiling DrywallInside AntennaAfter drilling the required hole, run the cable through and seal it with cable bushings, silicone or other waterproof sealant to enclose the hole that you have created. 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.In 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 up to 75 horizontal feet may be 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 15 inches for the Panel Antenna.Optional Wide Band Inside Antenna(sold separately)Multiple mounting options available

Ensure that both the Outside Antenna cable and the Inside Antenna cable are connected to the Signal Booster and the connections are tight before powering up the Signal Booster.3. Plug the power supply into the Signal Booster input marked “6V DC” (carefully, to avoid damaging the center pin). Note: It is very important to power your Signal Booster using a surge protected AC Power Strip with at least a 1000 Joule rating. Failure to do this will void your warranty in the event of a power surge or lightning strike.4. If the Signal Booster does not have a green light(s), please see pages 10-12.5. Using multiple Signal Boosters in one installation could cause interference to the cell tower (except for the In-Line Signal Booster).6.

The Signal Booster is equipped with one indicator light for the 700 MHz band. 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 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:Signal Booster Signal BoosterOutdoorAntennaOutdoorAntennaInside PanelAntenna Inside PanelAntennaFigure 1 Figure 2CORRECT INSTALLATION INCORRECT INSTALLATIONNever point antennas toward each otherPoint antennas away from each other

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 gain control until you get a blinking green light. The Signal Booster is now working with reduced gain. If the gain is not adequate for good coverage, you will need to turn the 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 reset. 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. Contact Wilson Electronics Technical Support Team for assistance: 866-294-1660.3. SOLID REDA red light indicates that the booster has shut down to prevent an A. oscillation, most likely caused by the Inside and Outside Antennas being physically too close to each other. Without this patented protection, oscillations could be transmitted to the cell tower, blocking calls to and from the cell tower. Oscillation occurs just like in an audio system when you put a microphone next to a speaker and get a big squeal. When the Inside Antenna is too close to the Outside Antenna the same type of oscillation occurs. If the booster has a red light, the following procedure needs to be done for each affected band.Either there is a problem with the Inside and Outside Antennas B. being too close together or there is a loose or bad cable (or possibly a defective booster). First, check the booster by unplugging the power cord, then removing the coax cables from the two connectors of the booster. Adjust the gain to minimum and plug the booster back in. You should now have a green light, if not, call Wilson Electronics Technical Support. Next, unplug the booster, reconnect the coax cables to the booster and tighten all connections, and plug the booster back in.Increase the gain until you get a red light (for example, it may C. be at 50 dB for the red light). This indicates that an oscillation occurs at gains 50 dB and higher. Separating the antennas is very important to get the necessary gain* for the system to give maximum coverage and a green light. Lowering gain decreases your coverage area. The Outside Antenna, if directional, needs to be pointed at the cell tower with its back to the Inside Antenna. The Inside Antenna needs to have its back facing the back of the Outside Antenna. Without proper orientation of the antennas, you will not be able to get maximum gain from the booster.

Hours: 7 am to 6 pm MST.Warnings and Recommendations Warning: The Directional Antenna must always be located so the back or side points to the Inside Antenna. Never point the front of the Outside Antenna toward the Inside Antenna – this is to prevent oscillation. Warning: Connecting the Signal Booster directly to the cell phone with use of an adapter will damage the cell phone. Warning: Use only the power supply provided. Use of a non-Wilson Electronics product may damage your equipment. Warning: RF Safety: All Inside Antennas used with this signal booster may not have gain (less cable loss) that exceeds 8.4 dBi and must be located at least 8 inches from all people. Outside fixed antennas may not have gain that exceeds 15 dBi (less cable loss) and must be located least 27 inches from all people. All antennas shown on page one meet these requirements. Warning: Verify that both the Outside Antenna and the Inside Antenna are connected to the Signal Booster before powering up the Signal Booster.Recommendation: Lightning Surge Protection is recommended for all in-building installations.*Note: If the antennas cannot be sufficiently separated, the booster will have to operate with reduced performance by decreasing the gain until a green light is obtained.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. This device complies with Part 15 of FCC rules.
