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. Areas implicated by this paragraph are those in which it is necessary to restrict radiation so as to minimize possible impact on the operations of radio astronomy or other facilities that are highly sensitive to interference. Due to the case load currently experienced by both the NRAO and Sugar Grove Research Station, expedited processing is highly unlikely. Exceptions to restrictions are usually determined on a case-by-case basis, with preference given to public safety concerns, such as remote alarm systems, repeaters for emergency services, and NOAA Weather Radio. Please include all required supporting documentation in your submission. We visited the US National Radio Quiet Zone as part of our trip to the Green Bank Radio Telescope and it wasn't as strict as we had been led to believe.

Antenna gain with horizontal and vertical patterns in one degree increments (in Planet or TIA-804-B Antenna File Format). Antenna location in latitude and longitude to nearest tenth of a second. The NRQZ Office reviews all applications to ensure that the computed power flux density at the reference point does not exceed frequency-dependent thresholds. Not all radio transmissions are prohibited in the core of the Quiet Zone. Establishing Quiet Zones: The final rule also provides an opportunity for localities nationwide to mitigate the effects of train horn noise by establishing “new quiet zones.” “No horn” restriction which may have existed prior to the establishment of the rule may be qualified to be “pre-rule quiet zones”. For a comprehensive list, click here. The entire property is designed as Zone 1 except small portions (such as housing, visitor, and laboratory areas) that are designed as Zone 2. It straddles the borders of Virginia and West Virginia, and also includes a sliver of Maryland. The NRQZ is a 13,000-square-mile area between Virginia and West Virginia, including a small part of Maryland, where the Allegheny Mountains act as a nat-ural barrier to radio and television broadcast. The Quiet Zone also protects the antennas and receivers of the U.S. Navy's Information Operations Command (NIOC) at Sugar Grove. The United States National Radio Quiet Zone is a stretch of land between Virginia and West Virginia in which radio transmissions and other sources of potential electronic interference are tightly controlled. Equipment t… The West Virginia Radio Astronomy Zoning Act (WVRAZ) and the National Radio Quiet Zone (NRQZ) were established to minimize possible harmful interference to the Green Bank and Sugar Grove facilities. The National Radio Quiet Zone (NRQZ) is a large area of land in the United States designated as a radio quiet zone, in which radio transmissions are heavily restricted by law to facilitate scientific research and the gathering of military intelligence.
