Page 5: Siting
4. Siting For best results, mount the 38485 facing towards the center of the coverage area with a clear line-of-sight path between the antenna and active floor. Avoid mounting next to a column or vertical support that could create a shadow zone and reduce coverage. A clearance of 0.91 m (3 ft) around the antenna is recommended. - Page 6 3. Use the hose clamps to secure the antenna to the mast or pole. FIGURE 5-2. 38485 mounted on a tower Wall mounting: FIGURE 5-3.
