The lower layers, the D and E layers are only a few tens of km - perhaps a hundred km at most. The F layers are of greater importance for ionospheric reflection, and may be up to 250 km. May be useful up to 800 km.
These various layers have a frequency - dependent reflectivity, and this will change day and night according to the state of ionization and the illumination causing that.
The ionosphere starts at an altitude of about 48 kilometers (30 miles) above the Earth's surface and extends upwards to about 965 kilometers (600 miles).
The ionosphere extends from about 30 miles (50 kilometers) to 600 miles (1000 kilometers) above the Earth's surface. The exact height can vary depending on factors such as solar activity and time of day.
The ionosphere is a region of Earth's atmosphere that starts at about 30 miles above the surface and extends upward to about 600 miles. It plays a crucial role in propagating long-distance radio communications by reflecting radio waves back to Earth. It also helps protect the Earth from solar radiation by absorbing and dispersing some of the energy.

Yes, the ionosphere is a layer of the Earth's atmosphere that extends from about 48 kilometers (30 miles) to 965 kilometers (600 miles) above the Earth's surface. It is composed of ionized particles that are influenced by solar radiation, playing a key role in the propagation of radio waves and communication.
The ionosphere starts at an altitude of about 48 kilometers (30 miles) above the Earth's surface and extends upwards to about 965 kilometers (600 miles).
The Ionosphere is the farthest layer from Earth among Troposphere, Stratosphere, Ionosphere, and Mesosphere. It extends from about 48 kilometers (30 miles) to 965 kilometers (600 miles) above the Earth's surface.

The ionosphere is the part of the earth's atmosphere extending from about 30 miles (50 Kilometers) to the exosphere that contains ionized atmospheric gases. it influences radio propagation to distant places on the Earth.
The ionosphere is a layer of earths atmosphere. It is charged with a high concentration of ions. It is above the mesosphere about 50 t0 600 miles above the earth.
The ionosphere extends from about 30 miles (50 kilometers) to 600 miles (1000 kilometers) above the Earth's surface. The exact height can vary depending on factors such as solar activity and time of day.

Electrically charged particles are found in the ionosphere, a region of the Earth's upper atmosphere that extends from about 48 kilometers (30 miles) to 965 kilometers (600 miles) above the Earth's surface. The ionosphere contains ions and free electrons that are formed due to the ionization of molecules by solar radiation.
The Radio waves are reflected back to Earth in the Ionosphere.
Electrified atoms, or ions, are plentiful in the ionosphere layer of the Earth's atmosphere. This layer is located between about 48 kilometers (30 miles) and 965 kilometers (600 miles) above the Earth's surface and is important for radio communication and the auroras.
The aurora occurs in the ionosphere of the earth, over 60 miles (80 km) above the surface of the earth. There is no vegetation there.
