Chapter 3: Planning The Installation
CHAPTER 3: PLANNING THE INSTALLATION
3.1 Installation Overview
Typically, a BDA installation follows these steps:
1. Decide what type of exterior antenna to use, and where to mount it. You will use either an omnidirectional
antenna, mounted vertically, or a directional Yagi antenna, pointed directly at the radio tower (line of sight).
The antenna will normally be mounted on the roof of the building or wall with the strongest signal. A ground-
ed lightning protector is required between the exterior antenna and the BDA.
2. Decide where to mount the interior antenna(s), being sure to take separation requirements into account.
Long, narrow spaces benet most from directional at-panel antennas, while more square spaces benet
more from omnidirectional dome antennas.
3. Decide where to mount the BDA. This should be in a secure indoor location near a grounded power source.
4. Decide where to route the cables between the exterior antenna and the BDA and between the BDA and
interior antennas.
5. Install the antennas as described in their respective Installation Manuals.
6. Route the cables to the BDA location.
7. Install the BDA as described in this manual.
8. Power on the BDA and perform conguration and testing explained in Chapter 5.
Important Installation Safety Precautions:
CAUTION: FAILURE TO PROPERLY INSTALL A
LIGHTNING PROTECTOR CAN RESULT IN DAMAGE
TO THE BDA, ANTENNAS, AND WIRING.
• Some components may be heavy and/or bulky. Always use proper lifting and carrying techniques when handling
components, especially when working on a ladder, roof, or other area with a fall hazard.
• 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.
