A rhombic antenna is a broadband directional antenna, mostly used in HF (high frequency, also called shortwave) ranges.
It is named after its "rhombic" diamond shape, with each side typically being of wavelength size. Each vertex is supported by a pole, several meters tall. It is fed at one of the sharp angles through a balun transformer, and is terminated at the opposite sharp angle with a non-inductive resistor. It is directional toward the resistor end, so fm antenna rhombic dipole it "points" toward the region of the world it is designed to serve.
The rhombic antenna can radiate close to the horizon or at rhombic antenna design a higher angle depending on its length, width, rhombic antenna calculator and height relative to the operating frequency. Likewise, its beam can be narrow or broad. A proper combination of size, height, and operating frequency make it fit for short- medium- or long-range communication.
Due to its considerable size, it is not very practical as the sole antenna of a radio design rhombic antenna station rhombic antenna desighn if operating conditions are expected to change rapidly. Moreover, it plainly requires a lot of land - especially if several must be combined to serve a variety of geographic targets at different rhombic tv antenna distance ranges and on widely different frequencies.
On the other hand, it is one of the best options for predictable point-to-point circuits. rhombic antenna Its very size give it a degree of gain, rhombic tv antenna dimensions and allow it to capture energy from a wide area, thus making it a little less susceptible to sharply localized fading than smaller antennas.
Electronics Topics
The field of electronics is the study and use of systems that operate by controlling the flow of electrons or other electrically charged particles in devices such as thermionic valves and semiconductors. The design and construction of electronic circuits to solve practical problems is part of the fields of electronic engineering, and the hardware design side of computer engineering. The study of new semiconductor devices and their technology is sometimes considered as a branch of physics.
