Sizes and dimensions for dipole antennas

When a stronger signal is needed, either to our favorite FM station on the radio or to our favorite TV channel, the most common solution we often turn to is the antenna. Antennas are available in various shapes and sizes, but mostly when you refer to something as an antenna, you always have one thing in mind: a structure similar to two pillars attached to a particular base and then installed on the roof this is only one form of the antenna, and arguably the most common form: the dipole antenna.

As the name suggests, the antenna is specifically characterized by having two posts made of material that serve as effective conductors, such as steel or iron. And since they are basically just two pieces of rods attached to capturing signals, they are often used because they are very practical and easy to manufacture.

Of course, the TV or radio will not be able to fully receive the benefits of the connected antenna if it were not for a particular connection that carries the signals. This connection can be operated with an RF transmission line, a coaxial cable or a balloon or RF transformer. Of these three options, many electronics experts suggest that balancing or shortening "balanced" and "unbalanced" is the most effective, as it ensures that the signal or radiofrequency, also known as RF, is well distributed over the antenna power line.

The right dimensions for a dipole antenna

To know what dimensions a dipole antenna should be, it is important to first know what its different types are. At this point, there are two most common types of a dipole antenna, the half-wave dipole antenna, and the folded dipole antenna. In fact, the last type is only a subtype of the first, but for instructional purposes, we both introduced here.

The half-wave dipole builds a wire antenna is basically what electronics experts consider to be the most efficient dipole antenna. The name basically refers to the location of the antenna, where it is located at half a wavelength over a conductive medium, such as the ground, a galvanized iron roof, or even on the water surface. This position uses a kind of bowling technique: it ensures that the signal stopping is correct and strong for the device that needs it. However, if we want optimum performance, we also need to ensure that this antenna is at many wavelengths away from potential radio frequency barriers, such as electric cables, support towers and other antennas.
