What are the advantage of trap dipole antenna?

Answer 1

A dipole antenna, is a radio antenna that can be made of a simple wire, with a center-fed driven element. It consists of two metal conductors of rod or wire, oriented parallel and collinear with each other (in line with each other), with a small space between them. The radio frequency voltage is applied to the antenna at the center, between the two conductors. These antennas are the simplest practical antennas from a theoretical point of view. They are used alone as antennas, notably in traditional "rabbit ears" television antennas, and as the driven element in many other types of antennas, such as the Yagi. Dipole antennas were invented by German physicist Heinrich Hertz around 1886 in his pioneering experiments with radio waves.

Answer 2

One example of a dipole antenna is the old style TV rabbit ears antenna, which is a folded dipole.

A dipole antenna is any antenna with 2 active elements. In a straight dipole the elements have the same axis. In a folded dipole the elements are at an angle to each other. Dipole antennas connect to the transmitter or receiver with balanced (frequently unshielded) and ungrounded transmission line.

Answer 3

A trap dipole lacks the efficiency, bandwidth, and often the directional pattern of a

full-sized one. Its main advantage is its smaller size, hence the ability to fit it into a

smaller available space. It may also be possible to use it on more than one frequency

band if the bands are harmonically related.
