The key objective of a good plan is to select sites that are acceptable form a technical standpoint as well as from cost and other non-technical considerations.
Many factors affect site selection.
The wise designer attempts to eliminate all risk of a site being rejected subsequent to the initial survey. The following preliminary steps assume that all the circuit requirements have been fully analyzed. Select radio locations, and if possible designate tall buildings for tower placement where feasible. Examine the topology between terminal sites on large-scale maps for potential routings to avoid obstructions. Select tentative routing, taking advantage of existing mountainous terrain for height advantages if a repeater point is required.
