Site Grounding and Lightning Protection

Site Grounding Lightning Protection Recommendations

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

One of the most important considerations when designing a communica-
tions 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 as follows:

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, 
telephone lines, and wires or cables connected to alarms or sensors located 
at the site.

RF Ground

This type of ground is related to the transmission of radio frequency ener-
gy to earth ground.  An example of rf grounding is the use of shielding to 
prevent or at least minimize the leakage of unwanted rf transmissions 
from communications equipment and cables.

Lightning Ground

Providing adequate lightning protection is critical to a safe and reliable 
communications site.  Telephone lines, rf transmission cables, and ac and 
dc power lines must all be protected to prevent lightning energy from en-
tering the site building.

Although a comprehensive coverage of site grounding techniques and 
lighting protection is not within the scope of this manual, there are several 
excellent industry sources for rules and guidelines on ground and light-
ning protection at communications sites.  

Motorola recommends the following reference source:

Motorola Quality Standards Fixed Network Equipment 
Installation manual, R56 . . . . . . . . . . . . . . . . . . . . . . . . . . . . .68P81089E50

Equipment Grounding Guidelines

The station is equipped with a  ground screw located on the rear of the sta-
tion Power Supply module.  This screw is used to connect the station to the 
site ground point.  It is assumed that all telephone lines, antenna cables, 
and ac or dc power cabling has been properly grounded and lightning pro-
tected by following the rules and guidelines provided in the above refer-
ence.
