YBA-4H-818-8085 all feed elements are constructed from a fully folded dipole welded to the boom, providing maximum bandwidth, excellent intermodulation performance and high reliability. The passive elements are thru mounted to the circular boom section which is fully welded to the mounting tube with a welded spacer between both booms before plating. The entire antenna is then plated in an alodine finish to provide an excellent conductive surface to ensure effective earthing of the antenna when it is mounted.


  • All welded construction for maximum and reliable performance

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

  • DC grounding on all elements for the ultimate in lightning protection and dissipation of static noise
