COMNAV2 Flashcards
It is an electrical device that converts electric energy into radio waves and vice versa. It is usually used with a radio transmitter or radio receiver.
ANTENNA
It is a device for sending or receiving electromagnetic waves.
ANTENNA
It is a device made of conductive metal (metal that conducts electricity) that sends and receives electromagnetic radio waves.
ANTENNA
Metal that conducts electricity

3 Factors to be considered while designing aircraft antennas:
The ENVIRONMENT to which Antenna is exposed.
The type of antenna used in each application will often depend on the SIZE OF THE AIRFRAME relative to the wavelength.
The most crucial consideration while deciding on the PLACEMENT of the antenna on the aircraft frame is the SAFETY OF FLIGHT.
3 Broad Categories Of Antennas
OMNI DIRECTIONAL
HIGHLY-DIRECTIONAL
SEMI-DIRECTIONAL
OMNI DIRECTIONAL
360 DEGREE
ALL DIRECTION
LOW GAIN
CONSUME MORE POWER
CAUSE INTERFERENCE
SHORT DISTANCE (LESS THAN 1MILE)
MULTI POINT COMMUNICATION
BROADER BEAMWIDTH
SEMI DIRECTIONAL
SPECIFIC ANGLE
LARGE AREA
MEDIUM GAIN
CONSUME LOW POWER
LESS INTERFERENCE
MEDIUM DISTANCE (UP TO 2MILES)
POINT TO POINT COMMUNICATION
HIGHLY DIRECTIONAL
SPECIFIED AREA ONLY
NARROW BEAM
HIGH GAIN
LOWEST POWER CONSUMPTION
MINIMAL INTERFERENCE
LONG DISTANCE (UP TO 35MILES)
STRICTLY POINT TO POINT COMMUNICATION
3 Basic Types Of Antennas Used In Aviation:
DIPOLE ANTENNA
MONOPOLE ANTENNA
LOOP ANTENNA
It is a type of RF antenna that includes two conductive elements.
DIPOLE ANTENNA
It is half of a dipole antenna on top of a conducting ground plane.
MONOPOLE ANTENNA
These antennas find uses in mobile communications and internet networks.
MONOPOLE ANTENNA
These type of antenna commonly found on aircraft.
LOOP ANTENNA
8 Aircraft Antenna Types For Different Purposes
COMMUNICATIONS ANTENNAS
GPS ANTENNAS
LORAN ANTENNAS
LOOP ANTENNAS
MARKER BEACON ANTENNAS
NAV ANTENNAS
RADIO ALTIMETERS
UHF ANTENNAS
They are there for effective communication
COMMUNICATION ANTENNAS
They are usually mounted on EITHER THE TOP OR BOTTOM of the aircraft and their only concern is being affected by the shadowing of the fuselage.
COMMUNICATIONS ANTENNAS
It transmit less than five watts of power, so by the time the SIGNAL reaches you, it is VERY WEAK.
GPS ANTENNAS
It has a built-in AMPLIFIER to boost the signal for the receiver.
GPS ANTENNAS
It be mounted at the top of the fuselage.
GPS ANTENNAS
Loran antennas also known as _______________.
LONG-RANGE ANTENNAS
It can be used in both communication and navigation.
LORAN ANTENNAS
Placed either on the top or bottom of the fuselage
LORAN ANTENNAS
