 The nearest "antenna farms" to Sharp's Ridge are on Holston Mountain in upper East Tennessee, home to most of the FM and TV stations in the Tri-Cities (Bristol, Virginia-Kingsport, Tennessee-Johnson City, Tennessee) Designated Market Area (DMA), and the Signal Mountain broadcast antenna farm, near Chattanooga, Tennessee, home to most of the FM and TV station antennas in that DMA.Although most radio and TV stations are in fierce competition with each other in their broadcast markets, they will often locate their broadcasting antennas very near each other, and in some cases, will even share land or towers with each other, in the interests of space, land availability, and the cost of putting a transmission building on top of a mountain.Other examples of co-located towers on mountain peaks in the United States are on Poor Mountain near Roanoke, Virginia; Red Mountain in Birmingham, Alabama; Mount Wilson near Los Angeles; Sutro Tower in San Francisco; Lookout Mountain, Colorado near Denver; Cedar Hill between Dallas and Fort Worth; South Mountain Park near Phoenix; Nelson Peak near Salt Lake City; Sandia Crest near Albuquerque, New Mexico; and probably the most famous broadcast antenna farm of all
