Contour Maps

Rule Section 73.3526(e)(4), 73.3527(e)(3)  
Retention As long as they reflect current, accurate information regarding the station.  
What's in here? These are graphical representations or "maps" of the area in which a broadcast station provides a particular level of signal strength over-the-air. They are useful, but general, indications of where service might be expected to be received from the station. They do not account, however, for the availability of a television station's signal carried by cable or satellite service providers, nor do they suggest that every point inside the contour will receive over-the-air service.
