should not be needed. If the Antenna is situated in an exposed position i.e on the top

of a multi-storey building the antenna should be grounded.

2. Run a 6mm stranded copper cable from the Antenna to a protection earth point i.e

building earth halo or earth provided specifically for lightning protection.

3. Secure the cable to the pole using straps and cleats as required

4. Fit a 6mm lug to the cable at the antenna end. Attach to the pole mount bracket

using the lower right M6 set screw as shown in Figure 20.

5. Connect to the earth point in accordance with local practice.
