RFI 16dBi YB820 Telstra Yagi Directional Antenna

 

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

 

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.

 

Usage

 

  • This is the highest performing Yagi antenna available

  • This antenna has been used by several mining companies to provide mobile phone reception over 80km to nearest phone tower

  • 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

  • The RFI Y820-81 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.

 

Measuring in at 2.4m, this Yagi is a solid piece of hardware that is often used for:

 

  • very flat outback locations
  • areas where transmission in the direction of the base station is clear of obstructions for several kilometres
  • when no service is available, even for several kilometres
  • when no other antenna cuts the mustard.

 

Higher Gain Yagi Antennas

 

  • To increase the gain of a Yagi antenna by 3dB you have to double its length
  • A good quality 16dBi Yagi measures around 2.4m in length, so you can imagine a 19dBi Yagi should measure between 4-5m in length - accordingly having a larger Yagi is not practical, instead higher gain is achieved by using grid antennas, such as the two models below.
