3.6 Antenna Specifications and Guidelines
Determine the antenna installation configuration, according to the transmission and coverage requirements and the
installation site conditions.
3.6.1 Authorized Antennas and Required Specifications
• RAU5x requires external broadband antenna - can be ordered with preassembled external antenna enclosure.
• External antennas - No limitation on any vendor of available external antennas with respect to the following requirements:
• Omni Directional or Directional
• Supported frequency range: wideband antennas supporting a range of 700 MHz to 2600 MHz
• Gain: up to 12.5 dBi
• Impedance: 50 Ohm
• Return Loss: +12 dB
• Number of antennas that can be connected (with cables/splitters) – it is not recommended to connect more than one
antenna per connector since 1:1 connectivity is reduced with each split.
• Types of couplers/splitters – depends on number of splits (not recommended)
3.6.2 General Installation Guidelines
• The RAU5x should be installed at a convenient location, free of metallic obstruction (can also be installed in plenum
spaces).
• Install the RAU5x at the designated height and tune it roughly toward the service coverage area.
• Installation of this antenna must provide a minimum separation distance of 20 cm from any personnel within the area.
• Cable and jumper loss is at least 2 dB.
3.7 Fiber Optic Requirements
3.7.1 Authorized Optic Cables
The following specified optic cables are authorized for use with the RAU5/RAU5x:
• Composite Plenum Tether Assemblies
• Fiber: LC APC, 2 – 24 fibers
• Cu: 16 AWG, 14 AWG, and 12 AWG; 2 – 12 Conductors
• Armored, non-armored
3.7.2 Fiber Optic Rules
• Use only or LC APC connectors
• UniCam connectors can be used for field termination
• Use only fusion splice for connecting two fibers
• Use minimum splicing/connectors to achieve minimum losses on the fibers (< 0.5 dB)
• Use precaution while installing, bending, or connecting fiber optic cables:
• Fiber optic cable is sensitive to excessive pulling, bending and crushing forces. Consult the cable specification sheet
for the cable you are installing.
• Do not bend cable more sharply than the minimum recommended bend radius.
• Do not apply more pulling force to the cable than specified.
• Do not crush the cable or allow it to kink. Doing so may cause damage that can alter the transmission characteristics of
the cable. The cable may have to be replaced.
