Site Grounding and Lightning Protection
CAUTION: 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.
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 sections.
12.1.6.1
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.
12.1.6.2
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.
