They are reflected back to Earth by the ionosphere as sky waves.
They penetrate terrain and buildings without any signal loss.
Question 2

To suppress background static and noise when no voice signal is being received.
To increase the transmitter power output.
To automatically switch between active and standby frequencies.
To adjust the pitch and tone of the received audio signals.
Question 3
Which frequency range represents the standard VHF aeronautical mobile communication band?
108.000 MHz to 117.975 MHz
118.000 MHz to 136.975 MHz
88.000 MHz to 108.000 MHz

Vertically, mounted on the top or bottom of the fuselage.
At a 45-degree angle to the aircraft centerline.
Coiled in a loop inside the cabin.
Question 5
What is a major advantage of HF (High Frequency) radio communications compared to VHF?
HF provides static-free and crystal-clear audio quality.
HF signals are not affected by atmospheric or solar disturbances.
HF signals can reflect off the ionosphere, allowing over-the-horizon, long-range communication.
HF radios require much smaller antennas and lower power.
