A map is defined as __________. - Answers -A graphic representation of a portion of the Earth's
surface drawn to scale, as seen from above.
Which of the following are the proper techniques for holding a compass and getting an
azimuth? Select all that apply. - Answers -Center-hold technique,Compass-to-cheek technique.
BASIC COMPONENTS OF RADIO EQUIPMENT - Answers -The radio equipment for
communication between two stations and the path the signal follows through the air is called a
radio link. A radio link consists of seven components: the transmitter, power supply,
transmission lines, transmitting antenna, propagation path, receiving antenna, and receiver. The
transmitter generates a radio signal. The power supply (i.e., battery or generator) supplies
power for the operating voltage of the radio.
When transmitting, the radio operator aims to provide the strongest possible signal at the site
of the receiving station. The best possible signal is the signal that provides the greatest signal-
to-noise ratio at the receiving antenna.
To transmit the best possible signal, select or determine the:
-Optimum frequency
-Best antenna for that frequency based on the available space of the transmitting site
-Proper propagation path

,The three types of radio modes are - Answers -simplex, half duplex, and full duplex.
-Simplex mode has one station that may send information over a single frequency. An example
of simplex mode would be AM/FM radio stations.
-Half duplex mode has information that can be transmitted and received in either direction, but
not in both directions simultaneously. An example of this is a single-channel two-way radio such
as a Motorola.
-Full duplex mode allows for an uninterrupted exchange of information between two stations. A
telephone would be an example of full duplex mode.
Tactical radio is - Answers -the principal means of communications support for MAGTF
maneuver units.
Principle characteristics of tactical radios:
-Easy to operate
-Networks are easily established
-Rapidly reconfigured
-Easily maintained on the move
-Secure voice communications
-Limited data information exchange
FREQUENCY BANDS AND CHARACTERISTICS - Answers -Each frequency band has certain
characteristics. The ranges and power requirements are for normal operating conditions (proper
siting, antenna orientation, and correct operating procedures). The ranges will change according
to the condition of the propagation medium and the transmitter output power. Using the

,correct frequency is extremely important. Never leave your frequency unless a higher
authorizes you to do so. Always ensure that you are using the correct frequency.
There are three tactical single channel frequency bands:
-High Frequency (HF) long-distance
-Very High Frequency (VHF) short-distance
-Ultrahigh Frequency (UHF) short-distance
High Frequency (HF) long-distance numbers: - Answers -Ground Wave Range = 0-50 miles
Sky Wave Range = 100-8000 miles
Power Required = .5-5 kW
Very High Frequency (VHF) short-distance numbers: - Answers -Ground Wave Range = 0-30
miles
Sky Wave Range = 50-150 miles
Power Required = .5 or less kW
Ultrahigh Frequency (UHF) short-distance numbers: - Answers -Ground Wave Range = 0-50
miles
Sky Wave Range = N/A
Power Required = .5 or less kW

, The primary advantage of using HF radio is - Answers -its capability to provide long-range, over
the horizon (OTH) communication. Successful data communications over the HF range depends
on several factors:
-Equipment siting
-Proper equipment grounding
-Types of antennas used
-Tactical employment of radio equipment
-Path assessment and analysis
-Frequency planning and assignment
Very High Frequency (VHF) - Answers -The primary MAGTF VHF radio is the single-channel
ground and airborne radio system (SINCGARS). SINCGARS is a family of lightweight combat
radios that serves as the primary means of communications for command and control and fire
support on the battlefield. SINCGARS is the standard VHF-FM tactical radio for the Marine
Corps. It replaced the AN/PRC-77 and the AN/VRC-12 family.
-The system provides high security against the threat of electronic warfare (EW) by using
frequency hopping with integrated COMSEC.
-It is capable of voice and data transmission (up to 16 kbps under optimum conditions and over
limited distances) over the VHF-FM frequency.
UHF radios are used for - Answers -forward air control (FAC) ground-to-air communication. Line
of sight between radios is critical for reliable communications. Significant range differences are
encountered between UHF radios employed for ground-to-air and ground-to-ground
communications. Greater range is achieved when employed from ground-to-air
communications because of the increased line of sight. When UHF radios are employed in the
