WMBR's Signal Coverage Area

The following image depicts WMBR's predicted coverage area:

• Red: Estimated F(50,50) field strength > 60 dBu - Signal should be strong
• Violet: Estimated F(50,50) field strength > 50 dBu - Signal may be medium to weak
• Blue: Estimated F(50,50) field strength > 40 dBu - Signal will be weak or unreceivable

• The red 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.
