1.6 How it Works
The GuardianA amplifies signals that reach a building from the nearest radio tower, and from radios inside the building going
back to the tower. This compensates for weak reception caused by distance, topography, building structure, etc. The BDA
receives the signal from an outside antenna, amplifies that signal, and then rebroadcasts it via antenna(s) inside the building,
where it can then be picked up by 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 exterior antenna for rebroadcast back to the tower.
1.7 A Word About Safety
Follow all safety precautions in this manual. This information is designed to prevent personal injury, equipment malfunction,
and/or radio interference. You are responsible for ensuring a safe installation.
Your installation may require working in high locations such as roofs and/or ladders. Follow applicable safety regulations and
best practices to avoid falling. Take care not to drop objects from any high area. Cordon off ground areas directly below the
section of roof you are working on, or below your ladder whenever possible.
In addition, as a qualified installer, you are responsible for knowing and following all applicable codes and regulations and for
obtaining all required permits and inspections.
Always use appropriate personal protective equipment such as goggles, gloves, hard hat, etc. as needed, and as required.
Failure to exercise caution when working in high areas could cause a fall and personal injury.

Planning the Installation
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, pointed directly
at the radio tower (line of sight). 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 separation 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 SureCall 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 external
antenna.
• Comply with all antenna separation requirements to prevent signal oscillation.
CAUTION: FAILURE TO PROPERLY INSTALL A LIGHTNING PRO-
TECTOR CAN RESULT IN DAMAGE TO THE BDA, ANTENNAS,
AND WIRING.
CAUTION: SIGNAL OSCILLATION CAN CAUSE RADIO INTERFER-
ENCE WITH RADIO TOWERS AND RESULT IN CIVIL AND/OR
CRIMINAL PENALTIES.
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:

SureCall | 48346 Milmont Drive, Fremont CA 94538 | 1-888-365-6283 | [email protected] 15
• 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.
• 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 provide
a 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:
Planning the Installation

SureCall | 48346 Milmont Drive, Fremont CA 94538 | 1-888-365-6283 | [email protected]
16
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 depends
on a number of factors, such as BDA gain level, building material, etc. Recommended separation distances are:
Amplifier gain Min. separation (ad)
40 dB 5’-6’
45 dB 15’-20’
50 dB 50’
55 dB 60’
65 dB 75-80’
70 dB 100’
75 dB 100’-120’
80 dB 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.
CAUTION: SIGNAL OSCILLATION CAN CAUSE RADIO
INTERFERENCE WITH RADIO TOWERS AND RESULT IN
CIVIL AND/OR CRIMINAL PENALTIES.
