Dual 16dBi Yagi Array Antenna Kit


Key Features


  • Highest performing kit available on the market

  • Fully welded construction for maximum performance and reliability.




  • The impressive 19dBi gain is achieved by routing and connecting two 16dBi Yagi antennas to function as one antenna array

  • This type of package is designed for the most remote and geographically challenging areas, where signal is almost non-existent

  • Phasing of antennas should be at a distance of between 850mm to 900mm

  • This antenna rests at ground potential and provides 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.

Quick Tip


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. Therefore, having a larger Yagi is not practical, instead higher gain is achieved by using grid antennas, such as the two models below:
