Note 1: FCC limit must be higher than Calculated/measured value. If not insert attenuation in 1 dB steps at CTU output to lower the RF power output.
If power output measurements are made at the CRE output, compliance must be determined by calculating power levels for both a and b outputs.
If power output measurements are made at the antenna input port, this measured value is listed in Column C and then compared
directly to the FCC limit.
Note 2: If power output of the CRE is measured, subtract the specified path loss in dB to determine to available input power to the antenna.
Note 3: The above table is provided as an example for this specific Canarsie installation and is preliminary. For other applications, the table will be
modified for the specific layout and will be made available.
