11.2 Detailed Installation
The recommended components for an installation protected for nearby strikes are:
• Recommended cables as described in Section 3.3.5.
• Lightning protection: Motorola PTP-LPU - 2 per link (2 Motorola Kits, part number 2978)
• Grounding Stake
• RJ45 screened connectors
NOTE: There may be a local regulatory requirement to cross bond the CAT 5e cable at regular
intervals to the mast. This may be as frequent as every 10 meters (33 feet).
Figure 96 includes illustrations showing the placement of the PTP lightning protection units and
