SerenityLine Antenna, Super High Performance, Single Polarized, 3ft

Rev : P2 | Rev date : 18 Dec 2020
RFS Class 4 and advanced Class 3 antennas are designed to provide the market’s best RF performance and allow mobile operators to deploy new microwave links even in ultra-dense areas where high levels of interference are present.

  • Available from 6 to 42 GHz frequency in both single (SL) and dual polarization (SLX) versions
  • Support for winds up to 250 km/h (155 mph) and even 320 km/h (195 mph) for 0.3m antennas diameter
  • An optional sway bar for antennas 1 m (3ft) and larger is available


  • Increase link capacity of the network
    Improved radiation patterns for ETSI Class 4 providing better performance
    Less interference and higher carrier-to-interference ratio
    Allows radios to operate at higher modulation levels
  • Minimize the total cost of ownership
    Improved network efficiency
    Facilitates better re-use of a frequency channel
    Small antennas with better link throughput reduces tower leasing fees
  • Easy to install
    Very low weight
    Compact mounting system
    Lower cost of installation
  • In-field upgrades – flexible feed design
    Upgrade from single to dual polarization in the field
    Build for the future – upgrade to the next generation radio in the field
