Measured Spectrum at the FedEx Field
Washington, DC
The following figures show the spectrum from TV channels 21 to 51, as observed
at Fedex Field on a spectrum analyzer with a ground plane vertical antenna having a gain
of approximately 0 dBi. The ESPN microphones are shown in red. The other frequency
labels indicate NFL microphones, spectral components of NTSC or DTV television
stations, or signals of unknown origin.
Figures E-1 to E-14 show the spectrum on the home team sideline of the playing
field, Figures E-15 to E-28 show the spectrum at the Tailgate area, Figures E-29 to
E-42 show the spectrum on the upper deck, and Figures E-43 to E-56 show the spectrum
in the press box. The ESPN microphones were turned on and off at each location.
Although the NFL was not expected to begin setting up and testing their
microphones until 5:00 PM, when making spectrum measurements on the upper deck
starting at about 3:00 PM, many new signals other than ESPN microphones appeared as
shown in Figures E-29 to E-42.  It was assumed that these were the NFL microphones for
which the frequencies were unknown.  Therefore, only the ESPN microphones were
identified by frequency labels in Figure E-43 to E-56, which show the spectrum with the
ESPN microphones turned on.
Figures E-57 to E-63 show the spectrum in the press box at about 6:20 PM, less
than one hour before the start of the game, and after the ESPN microphones had been
turned off permanently.  Except for amplitude, the spectrum is virtually the same as the
spectrum observed earlier in the day with the ESPN microphones turned off, as shown in
Figures E-43 to E-56.  Figures E-64 to E-70 show the spectrum during the first quarter of
the game.
When analyzing the data, be aware that the indicated frequency on the spectrum
analyzer is only an approximate value, and that there was a time delay of as much as one
and one half hours between measurements taken with the microphones off and on at a
given location.
The ESPN wireless microphones were operated on the following frequencies:
513.05, 525.3, 548.350, 576.2, 584.8, 594.5, 646.85, 653.15, 659.65, 670.15, and 682.3
MHz.
