Notes:
  • The blue 60 dBu contour designates WMBR's protected service area as defined by the FCC.
  • "dBu" refers to dB μV/m which is a logarithmic unit referenced to 1 microvolt per meter. See this Wikipedia article for more information.
  • "F(50, 50)" refers to the charts used by the FCC to predict the electromagnetic field strength occurring at 50% of receivers 50% of the time.
