Figure 5 – The antenna with log periodic elements in the vertical polarization. The elements can be pulled straight out and turned in either polarization, due to the square base connection. Figure 6 – ...

Most stations today transmit signals using horizontal polarization only. Of the 1,237 licensed DTV stations listed in my CDBS TV Engineering spreadsheet for Aug. 27, 2008, only 6.2 percent use any ...

So, in this simplified case, the direct signal arrives with its original rotation sense, say left-hand polarization, but the indirect signal arrives with right-hand polarization, and is rejected by ...
