10.1.6.2
RF Ground
This type of ground is related to the bypassing of unwanted radio frequency energy to earth ground. An
example of RF grounding is the use of shielding to prevent or at least minimize the leakage of
unwanted RF energy from communications equipment and cables.

10.1.6.3
Lightning Ground
Providing adequate lightning protection is critical to a safe reliable communications site. RF
transmission cables, and AC and DC power lines must all be protected to prevent lightning energy from
entering the site.

Comprehensive coverage of site grounding techniques and lightning protection is not within the scope
of this instruction manual, but there are several excellent industry sources for rules and guidelines on
grounding and lightning protection at communications sites.

Equipment Grounding
The SLR 1000 Repeater is equipped with a ground screw on the bottom right of the repeater.
This screw is used to connect the repeater to the site grounding. All antenna cables, and AC and DC
power cabling, should be properly grounded and lightning protected by following the rules and
guidelines provided in the previous sections. Failure to provide proper lightning protection may result in
permanent damage to the repeater.

Recommended Tools and Equipment
In addition to the typical compliment of hand tools, the following tools and equipment are
recommended for proper installation of the repeater equipment.
recommended for proper installation of the repeater equipment.
• Tarpaulin or plastic drop cloth or cover surrounding equipment while drilling concrete anchor holes.
• Vacuum cleaner for removing concrete dust caused by drilling.
