during temporary and short-duration peaks for which the rectifier output is insufficient.
Frequency
For a periodic wave, such as alternating current, the number of complete cycles per unit of time.
The unit of frequency is cycles per second, or hertz.
The unit of frequency is cycles per second, or hertz.
Fuse
An overcurrent protective device that has as its critical component a metal wire or strip that will
melt when heated by a prescribed (design) amperage, creating an open in the circuit of which it is
a part, thereby protecting the circuit from an overcurrent condition.

G
Gain
The ratio of output current, voltage, or power to input current, voltage, or power, respectively.
Gain is usually expressed in dB. If the ratio is less than unity, the gain, expressed in dB, will be
negative, in which case there is a loss between input and output.

Garmin 45XLS
A handheld GPS receiver that can be used to verify GPS reception at a cell site. It has a removable
antenna and provides +5 VDC on the center pin of the RF connection to power external active
antennas. If poor GPS reception is suspected, the Garmin 45XLS can be used to verify that the
GPS antenna and cable system is working acceptably. It will also verify that the GPS antenna
location is acceptable.

GFCI (Ground Fault Circuit Interrupter)
A device intended for protection of personnel that functions to de-energize a circuit or portion
thereof within an established period of time when a current to ground exceeds some
predetermined value that is less than that required to operate the overcurrent protective device of
the supply circuit.

GPS (Global Positioning System)
A system of 24 satellites that provides, among other things, extremely accurate timing information
to the cell sites.

Ground
A conducting connection between equipment or an electrical circuit and earth, or conductive body
that is used in place of earth.

Grounding electrode system
The conductive objects that are intentionally bonded to furnish connection to earth (i.e., buried
ring ground with ground rods, electrically continuous buried metallic water pipe, electrolytic
ground electrode, etc.).
