What is a wire dipole?

The dipole is a type of antenna that has two poles, also called elements, with one end of each pole located near one end of the other. The most famous type of dipole is the rabbit antenna used with TVs. The wire dipole antenna is essentially the same, except that the two poles are made of two pieces of wire rather than from metal bars as a set of rabbit ears. Wire dipole antennas can be used to accept many different types of radio transmission, such as television, radio or short -wave signals, with the total length of two poles determining the top efficiency of the antenna for a given frequency.

In terms of antenna surgery theory, the wire dipole is among the more equal types of radiofrequency antennas antennas due to its simplicity of operation and the fact that it is constructed from nothing more than two wire lengths. Tuning the wire dipole antenna on a particular frequency is also a simple matter that does not requireThere is nothing but a reduction in the wire length. The most common way to determine the correct length of the wire for the antenna is to reduce the wire, which is 95% of one half of the wavelength of the frequency to be accepted, and then cut the wire in half to make two poles of the antenna. Thanks to this, they are often referred to as half -waves antennas. Because these antennas are only half the length of the antenna full of wool, they take up much less space and make it easier to assemble.

In addition to being easier to design, the antennas of wire dipole are also easier to remove and move than antennas made of stricter materials, which may also require a support structure. This allows potentially very large wire dipole antennas to be built and deployed very easily anywhere, and if the situation requires, removed and moves easily. Small size needed for high frequencies also creates these types of antennastily small to put into the most comfortable spaces like spaces canWalls inside the windshield of the car for the FM radio antenna.

While the wire antennas are more efficient than monooelement models such as Whip -style antennas are not as efficient and versatile as other, more published dipole antennas. The primary reason is due to the diameter of the wire compared to the much larger diameter of the metal elements of the seat antennas. Ridged dipole antennas can also have more elements added in parallel with dipole elements that serve as directors and reflectors, which can significantly improve performance. Wire dipole antennas are simply too narrow to effectively cope with other elements.
