RFI YB6-61 450-480MHz UHF Yagi Antenna


Key Features


  • Fully welded 6 element construction

  • 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 designed & manufactured.




  • The YB6-61 feed element of each antenna is of full folded dipole construction thus offering maximum bandwidth and reliability

  • The dipole element is welded to the boom to ensure low intermodulation performance and maximum durability

  • The passive elements are through mounted to the circular boom section and welded at each side to further minimise the potential for both corrosion and generation of intermodulation products

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

  • Constructed with 2 to 16 elements, YB Series yagi antennas offer a choice of gain and beamwidth characteristics and can be configured in stacks or bays for higher gain applications in either horizontally or vertically polarised systems

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

  • Durathene polyethylene jacketed cable provides superior resistance to weathering and abrasion and is less susceptible to bird attack than standard PVC sheathed cables

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