STRIDE2400 Terminal Station Setup Guide
2.1.3 Grounding and Lightning Protection Guidelines
A well-constructed grounding system helps protect SR Telecom equipment from lightning strikes. To
properly ground the SR Telecom equipment, lightning rods, transmission lines, poles, and towers,
ensure that these guidelines are followed:
• A suitable grounding point is available where the electrical potential at the remote station and the
subscriber site is identical, and never exceeds a ground resistance of 10 Ω year round
• The lightning rods, antennas, and transmission lines are properly installed and grounded
• The transmission lines are installed as far as possible from the grounding wires
• The grounding wires are as straight as possible (no loops or sharp bends) and are routed toward
the nearest common ground connection
• The lightning rods provide approximately a 45° cone of protection, which will protect all equipment
under their field of coverage from direct lightning strikes
• All ground connections are tightly secured and made below the equipment being grounded
• All grounding wires are stripped and secured to bare metal using compression lugs at every
3 to 6 ft. (1 to 2 m)
• The transmission lines are grounded after the top curve and before the bottom curve
• The transmission lines are grounded to the common ground of the structure (tower, pole, building)
• Each piece of equipment must have a separate grounding wire that is grounded to a common point
• For towers and poles that are higher than 246 ft. (75 m), the transmission line must be grounded
every (98 ft.) 30 m
