Travis AFB Sustainability Study Report Final Background Report | Page 166

Frequency interference is related to other transmission sources . Interference can result from several factors , including :
• Using a new transmission frequency that is near an existing frequency ;
• Reducing the distance between two antennas transmitting on a similar frequency ;
• Increasing the power of a similar transmission signal ;
• Using poorly adjusted transmission devices that transmits outside their assigned frequency or produces an electromagnetic signal that interferes with a signal transmission ;

Radar impacts from wind tu Location of wind turbines sou radar field of view . Turbines This becomes more of an issu going through the radar on th the Bay Area . The County and Commission have adopted St limit any future geographic ex turbines are allowed .
• Existing electronic sources and uses created by portable systems affecting entire communities utilizing Wi‐Fi broadband systems ; and
• Industrial sources that produce electronic noise by‐product .
The military relies on a range of frequencies for communications and support systems . Since 1993 , Congress has been selling federal spectrum bands for reallocation to the private sector , promoting the development of new telecommunications technologies , products and services . The expanding public and commercial use of the frequency spectrum from wireless transmitters to consumer electronics can encroach on the military ’ s use of the frequency spectrum . Increasing community and DOD demands for this important resource can create conflicts for all users .
Compatibility Assessment
The High Winds , Montezuma Wind II , Shiloh I , S and Solano Wind farms are located in the Mont southeast of Travis AFB , and consist of over 600 heights of the turbines range between roughly ground level . The presence of these large , com present challenges to the Travis AFB flying miss ( RF ) interference , clutter , or screening . RF clutt turbines , have the potential to corrupt the accu to flight operations by the rotating turbine blad Doppler shift on the radar signal . Wind farms h increase in density of wind turbines .
