2. Hunan being invented the antennas long time ago and it has been
produced by antennas manufacturer and used by us for a long time
period Usually, we use it to receive the signals for our TV and radios
For TV and radio, we have to use the antennas to transmit and
receive electromagnetic waves, otherwise, our TV set and radio set
cannot pick up signals from the stations As a matter of fact, the
strength of the antenna as well as how to pick up the signals are
greatly decided how many channels you TV set and radio set are
able to pick up Besides that, where your antenna locate, its quality
and the weather also can exert the influences on the quality of the
transmission and the number of channels your TV set and radio set
can receive
3. Working Principle of TV Antenna We can see the TV antennas that
are set indoor and outdoor Usually, the indoor antenna is also
referred to half wave dipole antenna which features small size
These indoor antennas make full use of its "ears"to adjust the
lengths to improve the strong signals But the fact is that these
indoor antennas are not good as those mounted on the rooftops or
outdoors
4. The outdoor antennas are usually bigger in size and can receive
strong and better signals The only disadvantage of these antennas
is that the weather can easily affect the signals For instance, the
strong wind outside would change the location of the antenna so that
the signals would be disrupted In this case, you can set the TV
antenna on the highest diploe antenna windows of the building or on
the attic to cope with the problem
5. You would spend more to take the downside of outdoor antennas
Also, the distance of your location and the transmitter would affect
the quality of the signals You would pick up better and strong
signals if you stay close to the transmitter Working Principle of
Radio Antenna The working principle of a radio antenna and a TV
antenna is roughly similar - change the electric currents into the radio
waves and vice versa
6. It also has a transmitter and a receiver just like TV Its transmitter
uses radio frequency current to the terminals of the antenna which
radiates these radio waves (referred to electromagnetic waves too),
so the signals can be transmitted The reception process of the TV
antenna and the radio antenna is similar - using the terminals to
detect the signals and receiver decodes can be amplified You could
