2.2 Service Antenna Considerations
The Service antenna type depends on whether the Signal Booster is installed indoors or outdoors.
2.2.1 Required Information
The following antenna requirements, specifications and site considerations should be met.
• Type of installation – indoor or outdoor
• Service area size
• Height at which antenna(s) is/are installed
• Antenna type and characteristics
• Length and type of coaxial cable required for connecting the Service antenna to the Signal Booster and
the attenuation.
2.2.2 Indoor Installations
2.2.2.1 Recommended Antennas
The following describes the requirements for an omni-directional mobile used for indoor applications.
Specifications:
• One or a combination of the following antennas can be used: Ceiling Mount Patch antenna, Wall Mount
Patch antenna, Corner Reflector.
• Omni directional antenna with a 0 to 2 dBi typical gain, or wide beam with up to 10 dBi gain.
• Example of omni-directional antenna specifications:
Gain: 0 to 2 dBi
VSWR: < 2:1
Impedance: 50 ohm
• Choose an antenna with high side lobe attenuation that allows maximum isolation from the service/
mobile antenna.
• A minimum of 5 such antennas must be connected to the Signal Booster with cables and splitters.
• The maximum EIRP from each antenna shall not exceed 3W.
2.2.2.2 Installation Criteria
Installation requirements:
• An indoor antenna should be installed at a convenient location. It should be free of metallic obstruction.
• Install the Service Antenna at the designated height and tune it roughly toward the Service coverage
area.
• Installation of this antenna must provide a minimum separation distance of 28cm for FCC and 42cm for
IC, from any personnel within the area.
For D-SBR 4008 PS NFPA: the minimum distance for IC, is 57cm from all nearby persons.
Note: If the power is divided into more than 5 antennas that have a large coverage area than the
separation distance can be less than the given distance.
• Cable and jumper loss is at least 2dB.
