Antenna Structure An antenna array and its associated support structure, such as a mast or tower, but not to include a suspended simple wire antenna, that is used for the purpose of transmitting and/or receiving electromagnetic signals, including but not limited to radio waves. Antenna Structure, Freestanding An antenna structure or mast that is not attached to a building, fence or other such structure. Freestanding antenna structures include communications towers, wooden utility poles, standard or decorative concrete and steel monopoles. Antenna Structure, Lattice Freestanding or guyed (wire ground connections) steel structure frame. Base Station (Base Transceiver Station, BTS) A fixed station at a specified site authorized to communicate with mobile stations. Base stations are usually housed in metal cabinets or small structures within close proximity to the antenna structure, housing ancillary equipment and back-up power. Collocation (Co -location) 1) Siting multiple antenna structures within the same local area. Also called "antenna farms." 2) Multiple antennas attached to an existing or proposed freestanding antenna structure.
