One of the most important technical issues is <br />coverage. Essentially, this affects the number and height of <br />towers to adequately serve an area. RF engineering is the <br />technical method of determining coverage. This then affects tower <br />location and height. <br />Other technical issues relate`to coloration. Both technology <br />compatibility and tower structural characteristics affect <br />colocation. If technologies (cell, PCS, paging) interfere with one <br />another, colocation may not be possible. Similarly, the structural <br />characteristics of a tower, itself, may preclude installation of <br />additional antennae. <br />Besides those referenced above, other technical issues relate to <br />tower wind load design and fall radius, electromagnetic fields <br />(EMF's) for certain types of towers, tower lighting, and - <br />stealthing._ Associated with all of these technical issues is cost. <br />•Aesthetics and Land Use <br />Among all the tower issues, aesthetics is the most controversial. <br />As of this time, however, the aesthetics issue has not been <br />sufficiently narrowed down by the Board of County Commissioners or <br />the Planning and Zoning Commission. <br />Several components affect a tower's aesthetics. These include the <br />tower's lighting, its height, its bulk, guy wires, and others. To <br />regulate the aesthetic characteristics of towers, it is necessary <br />to determine which tower characteristics contribute to tower <br />aesthetic concerns. <br />Generally, towers have white strobe lighting during the day and a <br />red pulsating light at night. One issue to address is whether <br />tower lighting is an aesthetic <br />aesthetically unacceptable one <br />subdivision, are tower lights <br />subdivision?
