9.4 Radio Signal Propagation
9.4.1 Introduction
This section explains and simplifies many of the terms relating to antennas and RF
(Radio Frequency) used when dealing with an RF installation system.
The following diagram depicts a typical radio system:
Figure 9-6. Typical Radio System
A radio system transmits information to the transmitter. The information is
transmitted through an antenna which converts the RF signal into an
electromagnetic wave. The transmission medium for electromagnetic wave
propagation is free space.
The electromagnetic wave is intercepted by the receiving antenna which converts it
back to an RF signal. Ideally, this RF signal is the same as that originally generated
by the transmitter. The original information is then demodulated back to its original
form.
