Repeaters is usually erected on high sites, it is a receiver tuned to the original transmitters frequency on the other end a transmitter tuned slightly offbeat in other words a bit lower or higher frequency than it's receiver from where any receiver that is in sight can receive the signal.
Al the radio masts that is some times visible on mountains and hills are repeaters, the radio ham leagues in most countries have there own network of repeater that is used in the two meter band and higher, repeaters can not be erected on the ocean, so that is what satellites are for.

What is the different modes of the radio wave propagation?
Ground wave, sky wave and space wave propagation
What is meant by ground wave propagation?
Ground wave propagation refers to the transmission of radio waves along the surface of the Earth. This type of propagation is commonly utilized for medium and long-distance communication, particularly in the AM radio band. Ground wave signals can follow the curvature of the Earth, allowing for extended coverage compared to line-of-sight transmission.

Is a radio wave longitudinal?
No, radio waves are transverse waves, meaning the oscillation of the wave is perpendicular to the direction of wave propagation. Longitudinal waves have oscillations parallel to the direction of wave motion.
What is the space wave propagation frequency?
Space wave propagation frequency is nothing special, it is the same frequency of the wave in question, for example WLAN Wifi produces 5.2 GHz radio wave from your computer or from router, so that would be the the space wave propagation frequency in question

What are the applications of sky wave propagation?
Sky wave propagation is used in long-distance radio communications. It is commonly used for broadcasting, military communications, and amateur radio operations. Sky wave propagation allows signals to be transmitted over long distances without the need for expensive infrastructure.
What has the author Lucien Boithias written?
Lucien Boithias has written: 'Radiowave Propagation' -- subject(s): Tropospheric radio wave propagation
Is radio wave longitude or transverse?
A radio wave is an electromagnetic wave. Electromagnetic waves are transverse waves.
how does layer of ionosphere affects in the propagation of radio waves?
The ionosphere layer affects radio wave propagation by reflecting or refracting the waves back to Earth. Different layers of the ionosphere interact with radio waves of different frequencies, allowing for long-distance communication via multiple hops. Changes in the ionosphere's density and ionization levels can also affect radio wave propagation by absorbing or attenuating signals.
Is radio wave is a mechanical wave?
No, radio waves are not mechanical waves. They are a type of electromagnetic wave that do not require a medium (such as air or water) for propagation. Mechanical waves, on the other hand, require a medium to travel through.
