WMBR's Signal Coverage Area
The following image depicts WMBR's predicted coverage area:
- Blue: Estimated
F(50,50) field strength > 60 dBu - Signal should be strong
- Red: Estimated
F(50,50) field strength > 50 dBu - Signal may be medium to weak
Estimated F(50,50) field strength > 40 dBu - Signal will be weak or unreceivable
- 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.

- "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.
