Description: This dataset contains the spatial extent of AM tower structures in the state of Florida. AM stands for "Amplitude Modulation", which refers to the means of encoding the audio signal on the carrier frequency. In many countries, AM radio stations are known as "medium wave"(MW) stations. AM stations are also sometimes referred to as "standard broadcast stations", since AM was the first form used to transmit broadcast radio signals to the public. AM towers are unique in that AM stations have different operations for daytime and nighttime operation. This is because AM signals go further at night, due to atmospheric changes. Usually day and night operations are at the same site, but some may use different sites. These daytime and nighttime operations lead to duplicate records at the same location. Because we are only interested in tower locations and not individual AM stations for this particular dataset duplicate records representing day/night stations were removed.
Description: This dataset contains the spatial extent of FM Radio Station Transmitter sites in the state of Florida. FM stands for "Frequency Modulation", which refers to the means of encoding the audio signal on the carrier frequency. In some countries FM broadcast radio is referred to as "VHF."
Description: This dataset contains FCC registered television broadcast structure locations. Previously both digital and analog structures were included. Television broadcast has since transitioned to all digital transmission.
Description: This dataset contains locations from the antenna structures database that are required to register with the Federal Communications Commission (FCC). The FCC requires owners to register those antenna structures which generally are more than 60.96 meters (200 feet) in height or located near an airport.
