RFI 11dBi YB806 Optus/ISM Yagi Directional Antenna


Key Features


  • Fully welded construction for maximum performance and reliability

  • Extremely durable, long MTBF

  • Can be configured in stacks or bays for higher gain applications

  • Short low loss cable tail with N-female connector

  • Australian manufactured and warrantied.




  • This is a very high quality antenna designed for applications requiring high performance, low passive inter-modulation, and very low VSWR

  • This type of antenna is typically deployed in 3G/ISM M2M control applications such as smart metering, water monitoring, etc.

  • The YB806 Series are high gain Low PIM Yagi antennas which provide excellent point to point communications in RF control, short or long haul link, point to multipoint and other applications calling for highly directional antennas

  • YB806 Series antennas exhibit narrow beamwidths (comparatively) and high front to back ratios to help minimise any potential interference to and from other systems

  • The feed element of each antenna is of full folded dipole construction, welded to the mounting boom for maximum bandwidth, low intermodulation performance and reliability

  • The passive elements are through mounted to the circular boom section and welded at each side before plating

  • The alodine protective finish provides a conductive surface to ensure effective earthing of the antenna when mounting.
