The 2227-21X4CP is a high gain, Wave Guide Fed Yagi. Computer optimized for use in the 2210-2245 MHz band. Mechanically optimum computer calculations are held by CNC machined hex material for the element structure. The low-loss Polyethylene Radome covers and adds to the strength of the antenna. Vertical or Horizontal polarization is achieved simply by rotating the antenna 90 degrees.
