1. An antenna system for terrestrial broadcasting comprising:
- a dipole antenna probe for receiving a broadcast signal;
a signal amplifier for amplifying the received broadcast signal;
an antenna matching unit for matching impedances between the antenna probe and the signal amplifier;
an output matching unit for matching impedances between an output signal of the signal amplifier and an input terminal of a broadcast receiver to which the output signal is fed; and
a bias extractor for converting power received from the broadcast receiver into power required for driving the signal amplifier and supplying the converted power to the signal amplifier.
