Types of Grounds.
a. It is important that communication equipment be grounded. The
equipment ground is a safety measure that shunts a potential
electrical hazard to earth.
The standard ground rod issued with
communication equipment should be driven into the earth and then
attached to the shelter or equipment. When operating in a building,
a cold water pipe may be substituted for the ground rod connection.
b. Sometimes it is difficult to get a good ground, connection
especially in sandy locations.
Then you must treat the soil with
common table salt and water or coal dust and water. The area must be
retreated periodically in order to maintain a good ground connection.
c. A method of obtaining an artificial reflecting surface is
through the use of a radial ground system. The purpose of the radial
is to reflect the ground reflected wave and to add to the direct
wave. The radial ground system is an artificial ground or reflecting
surface used to compensate for the poor conduction quality of the
soil. The most common radial ground system is 36 lengths of wire a
tenth to a half-wave in length buried 6 to 8 inches and connected to
a ground rod.
