Definitions. For the purpose of this subsection, the following definitions shall apply:
ANTENNAA system of electrical conductors that transmit or receive radio waves.
CELLULAR TELEPHONEA system providing portable telephone service to specific subscribers. The system works on a line-of-sight principle. Each company must set up a "grid" system of antennas on hilltops to provide complete coverage.
COMMERCIAL COMMUNICATIONS TOWERA structure, partially or wholly exterior to a building, used for transmitting or retransmitting electronic signals. Commercial communications towers include, but are not limited to, a radio common carrier tower or an antenna used for transmitting commercial radio or television signals, microwave signals, cellular telephone communications and/or satellite communications. A commercial communications tower shall not include an amateur radio antenna or a satellite dish antenna (as defined by this section) or an emergency services radio antenna if such are accessory to a permitted use.
CONSTRUCTION PERMITA document issued by the FCC to a broadcast applicant giving permission to construct a radio or TV broadcast station. It is not the same as a station license.
FM/TELEVISION BROADCASTINGTransmission of radio and/or television programs intended for reception by the general public. An "FM/television broadcasting tower" shall mean a tower maintaining the primary or main transmitter of an FCC-licensed broadcast station.
HEIGHT ABOVE AVERAGE TERRAIN (HAAT)A technical term used by the FCC to determine the effective height of an antenna by considering the effects of terrain variations in the coverage area provided by the antenna.
HEIGHT OF TOWERThe overall height of the tower from the base of the tower to the highest point of the tower, including, but not limited to, antennas, transmitters, satellite dishes or any other structures affixed to or otherwise placed on the tower. If the base of the tower is not on ground level, the height of the tower shall include the base of the building or structure to which the tower is attached.
INTERMODULATIONA technical term referring to the possible mixing of two signals which creates unwanted and potentially interfering signals.
LAND-MOBILE SYSTEMSRadio communication service for mobile or stationary units in which each user is assigned a particular frequency. It includes conventional two-way radio, special mobile radio service and one-way paging.
LEASE TOWERA tower whose owner has as his principal business the leasing of tower space to other users.
POINT-TO-POINT MICROWAVECommunication between specific points using frequencies above 900 MHz; normally transmitted between two towers optimally located for line-of-sight transmission. Uses low power levels.
RF INTERFERENCEDisturbances in reception caused by intruding signals or electrical current.
STRUCTURAL CAPACITYA term describing the physical ability of a tower and associated antennas to withstand design loading without collapsing.
