Radio signals under 30 MHz (give or take) are reflected off the ionosphere back to Earth, whereas radio signals over 30 MHz (give or take) normally go straight through the ionosphere.
The maximum usable frequency (MUF) is the highest frequency reflected by the layers in the ionosphere. This frequency changes from day to night and with the seasons. It is also greatly affected by the 11 year sun spot cycle. Sun spots cause solar wind. This is a major cause for the ionisation of the ionosphere.

Portions of the atmosphere used to bounce shortwave radio signals around the world?
Ionosphere
What is a rf link transmitter used for?
An rf link transmitter is used to connect different repeaters together in a wireless network. A repeater is used to strengthen a wireless signal and provide better coverage.
Which type of electromagnet radiation is used in satellite communication networks?
Microwaves. These poke through the ionosphere to reach the satellite

Click on the link to your right for the weapons used.
Was the term ANZAC first used in world war 2?
No- it was first used in 1915- World War I. See link below-
Does the ionosphere bounce waves?
it just reflects waves radiated from the earth like telephone radiations and this is the thing that is used in satellites!
Sky wave antenna?
The term skywave is used to refer to the reflect radio waves from the ionosphere. ?æSkywave is used most frequently in shortwave radio broadcasts.
Why ground wave communication cannot be used for long distance using high frequency?
Frequencies over 30 Mhz normally travel through the ionosphere, whereas frequencies under 30 Mhz will normally bounce off the ionosphere, and back to earth.
Type of radiation stopped in the ionosphere?
Some, not all, radio waves. The reflected ones are the ones used for short-wave radio.
Part of atmosphere used to bounce shortwave radio waves?
Radio waves bounce off of the ionosphere and return back to Earth.
