This compensates for weak reception caused by distance, topography, and the building structure itself. The BDA receives the signal from an outside antenna (donor), amplifies that signal, and then rebroadcasts it via antenna(s) inside the building, where it can then be picked up by handheld radios inside. In the reverse direction, interior antennas also pick up signals coming from radios, where they are amplified by the BDA, and then passed to the outdoor (donor) antenna for rebroadcast back to the tower. 1.7 AWordAbout Safety Follow all safety precautions in this manual.

TowerIQ, Inc | 1609 Park 370 Place, Hazelwood, MO 63042| 844-626-7638 | cs-guardian@tower-iq.com 14 CHAPTER 3: PLANNING THE INSTALLATION 3.1 Installation Overview Typically, a BDA installation follows these steps:

1. Choose a mounting location for the exterior antenna. The recommended Yagi directional antenna is installed and pointed directly at the AHJ designated radio tower (line of sight) and away from the interior of the building on which it is mounted. The antenna is typically mounted on the wall or roof of the side of the building with the strongest signal. A grounded lightning protector is required between the exterior antenna and the BDA. 2. Next, choose the mounting location of the interior antenna(s), being sure to take isolation requirements into account. Long, narrow spaces benefit most from directional flat-panel antennas, while more square spaces benefit more from omnidirectional dome antennas. 3. Choose where to mount the BDA. This should be in a secure indoor location near a grounded power source. 4. Map the cabling route between the exterior antenna and the BDA and between the BDA and interior antennas. 5. Proceed with a soft installation connecting components without securing their placement until testing can be completed. 6. Power on the BDA and perform configuration and testing explained in Chapter 5. 7. Complete installation by securing the placement of the BDA, antennas and other components, Important Installation Safety Precautions:

The exterior antenna must not be co-located or operating in conjunction with any other antenna. Always use a properly installed TowerIQ lightning protector between the exterior antenna and the BDA. Always power off the BDA before working on the roof of the building, or anywhere in close proximity to the outdoor antenna. Comply with all antenna isolation requirements to prevent signal oscillation. CAUTION: FAILURE TO PROPERLY INSTALL A LIGHTNING PROTECTOR CAN RESULT IN DAMAGE TO THE BDA, ANTENNAS,AND WIRING. CAUTION:SIGNALOSCILLATIONCANCAUSERADIOINTERFER-ENCEWITH RADIO TOWERS ANDRESULT IN CIVILAND/OR CRIMINALPENALTIES. 3.2 Exterior Antenna Overview The Yagi antenna receives and transmits signals over a focused area. It must be aimed directly (line of sight) toward the radio tower that provides the strongest signal to the building. The exterior antenna and mast (if any) must be mounted in a location that meets all of the following criteria:

Best signal strength. Not co-located with other antennas or used in conjunction with other antennas. Away from all power lines. At least 6 ft. from lightning rod antennas. TowerIQ, Inc | 1609 Park 370 Place, Hazelwood, MO 63042| 844-626-7638 | cs-guardian@tower-iq.com 15 At least 8 in. from any person. These distances are general guidelines only. Refer to the applicable building and electrical codes in your area to determine specific local requirements. 3.3 Interior Antenna Overview You may use any combination of omnidirectional (dome) and/or directional (flat panel) interior antennas to obtain balanced signal strength throughout the structure. Dome antennas provide 360-degree hemispherical coverage suitable for mostly square areas, while flat panel antennas providea focused zone of coverage suitable for long narrow areas. The example above uses two dome antennas and one panel antenna to provide full coverage. Keep in mind that floor structures in multistory buildings can cause significant signal loss, which means that you may need to install interior antennas on more than one floor. Here is an example of a multistory installation:

Note: You may not need antennas on every floor of a multistory building, depending on factors such as building material, BDA gain, etc. 3.4 Antenna Separation Proper antenna separation prevents signal oscillation (feedback) that can interfere with the radio tower. Separation is measured in a straight line from the exterior antenna to the closest interior antenna. The closest allowable distance dependson a number of factors, such as BDA gain level, building material, etc. Recommended separation distances are:

TowerIQ, Inc | 1609 Park 370 Place, Hazelwood, MO 63042| 844-626-7638 | cs-guardian@tower-iq.com 16 Amplifier gain 40 dB 45 dB 50 dB 55 dB 65 dB 70 dB 75 dB 80 dB Min. separation (ad) 5-6 15-20 50 60 75-80 100 100-120 120-180 Vertical separation is more important than horizontal separation. If you are unable to obtain the required separation horizontally, try raising the exterior antenna. You may also try reducing the BDA gain as described in Chapter 5 of this manual. Antenna Safety Precautions:

You can mix and match dome and directional antennas as needed to obtain proper coverage throughout the building or area where you need to boost the signal. If you use a Yagi exterior antenna, you should normally aim it away from all interior antennas, regardless of separation, to prevent oscillation. Antenna Aiming OK CAUTION: SIGNAL OSCILLATION CAN CAUSE RADIO INTERFERENCEWITH RADIO TOWERS AND RESULT INCIVIL AND/ORCRIMINALPENALTIES. TowerIQ, Inc | 1609 Park 370 Place, Hazelwood, MO 63042| 844-626-7638 | cs-guardian@tower-iq.com 17 Indoor dry. Ambient air temperature is 25C. Away from tightly enclosed or overly hot spaces. Power and warning lights are easily visible. Shortest possible cable runs to all antennas. 3.5 BDALocation Select an indoor location for the BDA that meets the following criteria:

3.6 Accessories The final step in the planning process is to make sure you have all of the necessary accessories to complete the installation.You will need all of the items listed in Chapter 1 of this manual plus some or all of the following:

Hand and/or power tools as needed to complete the installation. Cable clips: Use these to secure the cables to interior and exterior walls/ceilings. Appropriately rated sealant/caulking to waterproof exterior cable entry points. Personal Equipment (PPE): Use all PPE required by local codes and/or best practices to help ensure personal safety duringinstallation. CAUTION: YOU ARE RESPONSIBLE FOR ENSURING THAT THE INSTALLATION MEETS ALL APPLICABLE CODES. Note: You may need to obtain a permit from your local building department to install the BDA and antennas. Check your local building and/or electrical codes. 3.7 NeedHelp?

In the event of any system malfunction, please contact a licensed installer. Caution: De-Energize Unit Prior to Servicing. 6.4 Testing& Troubleshooting Once the booster is powered on (and no Warning lights are on), assess the signal in locations of needed signal improvement. Refine the antenna locations and/or gain levels as needed, then complete the permanent installation when you are confident the system will perform well. A few tips and some perspective:

Its not realistic to expect full reception everywhere in the building. As a general rule, increasing gain by 6dB doubles the coverage distance of the interior antennas. Start at the lowest gain and increase gradually as needed. IfoneormoreredWarninglightscomeson, itindicatesthereis oscillationin thatbandandadjustmentsareneeded. If you cant get the coverage reasonably well-balanced, you may need to install an additional interior antenna and/or a different type of interior antenna and/or relocate interior antennas.
