Site Grounding and Lightning Protection

!
!
W A R N I N G
One of the most important considerations when designing a communications site is the ground and
lightning protection system. While proper grounding techniques and lightning protection are closely
related, the general category of site grounding may be divided into the following section.
1.6.1

Electrical Ground

Ground wires carrying electrical current from circuitry or equipment at the site is included in the
category of electrical ground. Examples include the AC or DC electrical power used to source
equipment located at the site, and wires or cables connected to alarms or sensors located at the site.
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.
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 repeater is equipped with a ground screw located on the rear of the repeater power supply
module. 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 above reference.

Proper site grounding and lightning protection are vitally important
considerations. Failure to provide proper lightning protection may result in
permanent damage to the radio equipment.
