2,500 Antennas and

The San Francisco Neighborhood Antenna-Free Union (SNAFU) is a grass-roots, city-wide coalition of individual residents and neighborhood organizations that works to prevent the placement of wireless antennas on or near residences, schools, health care centers, day care centers, senior centers, playgrounds, places of worship, and other inappropriate locations in the City and County of San Francisco.

The siting of cellular phone base stations and other cellular infrastructure such as roof-mounted antenna arrays, especially in residential neighborhoods, is a contentious subject in land-use regulation. Local resistance from nearby residents and landowners is often based on fears of adverse health effects despite reassurances from telecommunications service providers that international exposure standards will be followed. Likewise, it is a matter of debate that Wi-Fi signals have negative effects on human health. The most commonly used IP address to access the Router WiFi management interface is Both anecdotal reports and some epidemiology studies have found headaches, skin rashes, sleep disturbances, depression, decreased libido, increased rates of suicide, concentration problems, dizziness, memory changes, increased risk of cancer, tremors, and other neurophysiological effects in populations near base stations. The objective of this paper is to review the existing studies of people living or working near cellular infrastructure and other pertinent studies that could apply to long-term, low-level radiofrequency radiation (RFR) exposures. While specific epidemiological research in this area is sparse and contradictory, and such exposures are difficult to quantify given the increasing background levels of RFR from myriad personal consumer products, some research does exist to warrant caution in infrastructure siting. Further epidemiology research that takes total ambient RFR exposures into consideration is warranted. Symptoms reported today may be classic microwave sickness, first described in 1978. Nonionizing electromagnetic fields are among the fastest growing forms of environmental pollution. Some extrapolations can be made from research other than epidemiology regarding biological effects from exposures at levels far below current exposure guidelines.

SNAFU's work follows from the mounting evidence concerning the health and environmental effects of radiofrequency (RF) radiation used by cellular phones, cellular antennas and other wireless transmitters, as well as a commitment to responsive local government and community-based, democratic control over land use, zoning, and health & environmental issues.

News and Events

Wireless industry agrees to voluntary microcell antenna moratorium.
On February 13, 2007, Board of Supervisors President Aaron Peskin introduced legislation imposing a 45-day moratorium on microcell antennas throughout San Francisco, while the Planning Department and Board of Supervisors consider legislation that would require all microcell antennas in the City to undergo the Conditional Use permit process. Currently, microcell antennas require only Accessory Use permits which result in no public notification of antennas proposed for residential buildings. (Read the Feb. 23, 2007 article in the San Francisco Examiner here.) All 11 Supervisors co-sponsored Supervisor Peskin’s moratorium legislation.

On March 6, 2007, the day of the scheduled Board vote on the moratorium, Supervisor Peskin announced that the wireless industry had voluntarily agreed to suspend applications for microcell antennas and the Board therefore continued its vote on the Board-imposed moratorium for 45 days.

This marks a major victory for San Francisco residents who have been resisting the placement of microcell antennas on or near their residential buildings. Currently, antennas proposed for mixed-use apartment buildings at Fulton & Masonic near the Panhandle and Guerrero & 18th Street in the Mission are scheduled for hearings at the Board of Appeals on Wednesday, August 1, 2007 beginning at 5:00 p.m. in Room 416 at City Hall.

Stay tuned for more information on these two appeals as the microcell legislation process unfolds.
