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
• 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
• Types of couplers/splitters – depends on number of splits
• Couplers – Use N-Male to N-Female broadband coupler separately ordered from Corning (P/N AK-1COUPLER-NM-NF)
or the equivalent:
• Broadband frequency: 300 – 3000 MHz
• -20 dB coupling (SMA coupling port)
• Max. VSWR/Return Loss:12 dB
• Max. Insertion Loss (dB): 0.2
• 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 MRU should be installed at a convenient location, free of metallic obstruction (can also be installed in plenum spaces).
• Install the MRU at the designated height and tune it roughly toward the service coverage area.
• Installation of this antenna must provide a minimum separation distance of 100 cm from any personnel within the area.
• Cable and jumper loss is at least 2 dB.
