LIGHTNING PROTECTION

Proper grounding and cable routing is the single most important aspect of lightning

protection and RFI (radio frequency interference) reduction. We recommend reading

technical books or articles written by knowledgeable experts on grounding, rather than

relying on hearsay or folklore. As a general rule, anything done to improve lightning

protection also improves RF grounding and reduces unwanted RF interference.

Each piece of equipment at the operating position should connect to a common ground

point, or common ground buss.

The ground connection from the station should be made with wide smooth copper

flashing or tubing to a good earth ground.

The outside ground should be connected to the power line ground and telephone company

ground with the shortest-possible heavy conductor.

The outside ground should use multiple ground rods, and ideally should include several

buried wires to spread lightning current out over a large surface area.

All leads leaving a tower or mast should come down to ground level and exit the area of

the tower at or below ground level.

The tower or mast should be properly grounded.

The RCS-10 outdoor unit should be mounted directly to the tower or mast on grounded

tower or masts, or to a well-grounded metal post when tower mounting is not desirable or

practical.

The best protection is to disconnect antennas leads, although that is generally not

necessary with proper installation and grounding.

NOTE: Good lightning protection requires use of wide, smooth, copper flashing or

large, round, smooth conductors for ground leads. Avoid using braided or

woven conductors for ground leads, unless the lead has to be repeatedly flexed.

If you desire additional lightning protection, you can ground the "ANT 1" port of the

RCS-10 Relay Box by attaching a shorted connector. This connects the feedline center

conductor to the shield whenever power is removed, and opens all other antenna leads.

The main drawback is this reduces available antenna ports to seven.

impossible to guarantee immunity from lightning damage, grounding position one will be

a large step towards that goal.
