The VHF system uses independent transceivers but share the same antenna:
TRUE
FALSE
The HF system uses independent transceivers but share the same antenna:
TRUE
FALSE
Complete: As a result, transoceanic aircraft often use HF radios for voice communication. The frequency range is between 2 to (a) Mhz. These kinds of radio waves are known as sky waves.
Typically de HF antenna is located :
On the leading edge of horizontal stabilizer
On the leading edge of vertical stabilizer
Over any point along fuselage
The HF modes for modulation in most airplanes are:
AM and USB
FM and USB
AM and LSB

HF system cannot be used inside a hangar
HF system can be used near to open fuel cells
Normally the HF system antenna coupler is installed:
In the Avionics compartment
In the cargo compartment
Near to the HF antenna
The satellites used for communication are classified as:
LEO, MEO, HEO, GEO
GPS, GLONASS, GALILEO, COMPASS
The segments used for SATCOM are:
Space, Ground, User
Space, IT facility, User
