HF communication

High Frequency communication refers to radio communication in the range of frequency between 3-30 MHz or 3 000 000 – 30 000 000 Hz. The wave length range of High Frequency is 10-100 meters The Higher the frequency the shorter the wave length. High Frequency belongs to the radio portion of the electromagnetic spectrum. When electric current is sent back and forth through a wire an electromagnetic wave is created which can be amplified and transmitted out through an antena. It can then be received by a receiver which takes that electromagnic signal and turns it back into and electric signal and can be tuned to a specific frequency in this case 3-30 MHz for HF. If the radio waves are sent out at an angle the signal can sent into the atmosphere where it is reflected by the ionized atoms in the ionosphere and received at great distances.High Frequency communication refers to radio communication in the range of frequency between 3-30 MHz or 3 000 000 – 30 000 000 Hz.
