Preliminary Evaluations


As a service to applicants who are planning to install transmitters within the NRQZ, our NRQZ Office can evaluate proposed transmitter installations long before an applicant decides upon a final transmitter location or equipment configuration. These preliminary evaluations can help the applicant determine the best location for a transmitter while keeping NRQZ interests in mind and can ultimately expedite the application process. The result produced by the preliminary evaluation is the maximum power that can be radiated by the proposed transmitter towards Green Bank. Requests for preliminary evaluations should be submitted to the NRQZ Office and should contain the following information:

  • Name and address.
  • Radio service.
  • For each proposed transmitter:
    • Frequency or frequencies
    • Signal Bandwidth (if unknown, this information can be gathered from the technology type or the emission designator)
    • Antenna location in latitude and longitude to nearest second.
    • Antenna site ground elevation above mean sea level (AMSL).
    • Antenna height above ground level (AGL).

Concurrence letters are NOT provided with this type of evaluation. Applicants, should they decide to proceed with the development of facilities associated with any preliminary study, will have to complete the coordination process by providing ALL appropriate final system configurations, applications and engineering. See  “Methods of NRQZ Coordination” for further details.
