Should the straight wire antenna of a radio be vertical or horizontal to best receive radio waves broadcast by a vertical transmitter antenna? How should a loop antenna be aligned to best receive the signals? (Note that the direction of the loop that produces the best reception can be used to determine the location of the source. It is used for that purpose in tracking tagged animals in nature studies, for example.)

Antenna: An antenna, also known as an aerial, is a device that connects radio waves traveling through space with electric currents flowing through metal conductors.

In a straight transmitter antenna, the signal is flowing within the sort of the electrical current that flows along the length of the antenna causing the rear and also the fourth movement of the charge within the same direction. So, the charge moves during a vertical plane within the case of a vertical transmitter antenna. the electrical field is going to be within the vertical plane.

Therefore, the flux is going to be within the horizontal plane.

For receiving the radio waves in the best way, the receiver antenna and also the force field should be within the same plane. Because the force field is within the vertical plane, the receiver antenna should even be within the vertical plane.

So, the straight wire antenna of the radio should be vertical to best receive broadcast by a vertical transmitter antenna.

If the receiver antenna is placed horizontally, this thanks to the electrical field won't be induced within the receiver antenna.

Therefore, similarly within the loop antenna, the receiver antenna should be aligned within the plane of the electrical field to receive the wave signal in the best way.
