Dual output high frequency header production method ----- LNB

Keywords: high frequency head Author: Cao Guomin First, buy two of the same C-band high frequency heads (Gauss Bell 2200 or Baston, Ji-Da), unplug the two high-frequency headed waveguides, then use a steel saw to use two high frequencies One is separated by isolation needles, one and isolation needles cross 90o saw, be careful not to hurt or hurt two polarization probes, finally put the two high-frequency headed cuts smooth, then spell together, The upper waveguide, and then seals the cutting glass. When debugging, first adjust the antenna with a high frequency head that has not been converted, and then replace the original high frequency head with the high frequency header, first adjust the polarization angle of one of the high frequency heads (A heads). Another high frequency head (B head) polarized angle is just a polarization angle of the A head is 90o angle. Take the Asian 3S as an example, the A head receiver is normal polarization reception, and the polarization mode set by the B head receiver is in contrast, in the report parameter modification bar, the built-in The polarization parameter level is changed vertically, for example, change the phoenix TV to 4000, V, 26850, and modify the vertical polarization to the horizontal polarization, such as the central set of central, H, 4420.
