Why do I need an antenna to receive broadcast signals?

133 views  May 9, 2023
Broadcast signals are electromagnetic waves that propagate freely in space. The antenna works as an interface or media converter from these electromagnetic waves to conducted waves. Simply put, the antenna collects the airwaves, either very weak or very strong. In addition, depending on the distance to the television transmitter and other factors such as altitude, trees, hills/mountains and buildings, the signal strength may be reduced. Signals can be amplified at the antenna, as we do, downstream of the coaxial cable antenna, or even, in the case of very strong signals, the antenna may not need an amplifier.
