Measured Spectrum at the Majestic Theatre
New York City, NY
The following charts show the spectrum from TV channels 21 to 51, as observed 
at the Majestic Theatre on a spectrum analyzer with a ground plane vertical antenna 
having a gain of approximately 0 dBi.
Figures F-1 to F-14 show the spectrum on the sidewalk at the entrance to the 
theater, Figures F-15 to F-28 show the spectrum at the middle of the mezzanine, Figures 
F-29 to F-42 show the spectrum in the orchestra area, row I, stage right. The 
microphones were turned on and off at each location prior to the performance. Figures 
F-43 to F-49 show the spectrum on the entrance ramp to the orchestra area, stage left, 
during the first act of the performance. The on-stage microphones are indicated in red.
In addition to the eight on-stage microphones used during the testing and during 
the actual performance, the spectrum scans revealed the spectral signatures of NTSC and 
DTV television stations, and other narrow band signals.  Since the Majestic Theatre is in 
close proximity to several other theaters, which also use wireless microphones, it is 
believed that the other narrow band signals were most likely from those other theaters.  
When analyzing the data, be aware that the frequencies shown are approximate, and that 
there was a time delay of as much as two hours between measurements with the 
microphones off and on at a given location.
The on-stage wireless microphones were operating on the following frequencies:  
529.875, 542.125, 545.575, 600.275, 621.0, 665.8, 674.125 and 675.0 MHz.
