Table Mountain National Radio Quiet Zone

The Table Mountain National Radio Quiet Zone (NRQZ), located north of Boulder, Colorado is designated as an area where the magnitude of undesirable radio waves is restricted to minimize radio frequency interference on highly sensitive research projects.

Transmissions observed at Table Mountain include radio emissions from satellites, solar noise, and other radio astronomical sources. Work performed at the site provides information on radio propagation factors affecting the use of radio systems. The emphasis of the research work at Table Mountain is on long-range radio transmission problems and wave propagation studies.

The facilities at the site include two 60-foot satellite dishes. These structures are designed to accommodate temporary research projects, including radio astronomy and reception of weak satellite signals.
