RFI 16dBi Optus 900MHz Yagi Directional Antenna


Key Features


  • Fully welded construction for maximum performance and reliability

  • Narrow beamwidth & high front to back ratios effective in reducing interference

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

  • Short low loss cable tail with N-female connector

  • Australian manufactured and warrantied.


Additional Information


  • This antenna rests at ground potential and provide excellent lightning protection and reduced precipitation static noise

  • Termination is via an 'N' female coaxial connector fitted to a short 9302 Durathene cable tail

  • Durathene is a PTFE dielectric and polyethylene jacketed cable providing superior resistance to weathering and abrasion and is less susceptible to bird attack than standard PVC sheathed cables.




  • This is the highest performing Yagi antenna available

  • This antenna has been specifically designed for long range and very poor signal areas - a quality antenna designed for long term domestic, commercial and industrial applications

  • If you're having serious problems with your Optus broadband internet or mobile phone signal, the performance of this high quality fully welded aluminium antenna cannot be matched

  • The YB820 series has been used by several mining companies to provide mobile phone reception over 80km to nearest phone tower

  • Measuring in at 2.3m, this Yagi is a solid piece of hardware that is often used for:

    • very flat outback locations

    • areas with only one cell tower

    • when signal is very weak outside or even on the roof

    • when no other antenna cuts the mustard.
