A gas-filled tube can also be used as a shunt, particularly in a lightning arrester. Neon and other noble gases have a high breakdown voltage, so that normally current will not flow across it. However, a direct lightning strike (such as on a radio tower antenna) will cause the shunt to arc and conduct the massive … See more In electronics, a shunt is a device that creates a low-resistance path for electric current, to allow it to pass around another point in the circuit. The origin of the term is in the verb 'to shunt' meaning to turn away or follow a different … See more In photovoltaics, the term is widely used to describe an unwanted short circuit between the front and back surface contacts of a solar cell, usually caused by wafer damage. See more Where devices are vulnerable to reverse polarity of a signal or power supply, a diode may be used to protect the circuit. If connected in series with the circuit it simply prevents … See more One example is in miniature Christmas lights which are wired in series. When the filament burns out in one of the incandescent light bulbs, the full line voltage appears … See more Capacitors are used as shunts to redirect high-frequency noise to ground before it can propagate to the load or other circuit components. See more The term shunt is used in filter and similar circuits with a ladder topology to refer to the components connected between the line and common. … See more When a circuit must be protected from overvoltage and there are failure modes in the power supply that can produce such overvoltages, the circuit may be protected by a device commonly called a crowbar circuit. When this device detects an overvoltage it … See more WebA shunt antenna mountable on an aircraft comprises a lower plate, an antenna element formed above the lower plate and integrated within a dorsal fin of the aircraft where the antenna element is substantially slant relative to the lower plate; one or more couplers formed on the lower plate and operatively connected to a lower forward end of the …
How to shunt feed your tower - YouTube
WebMay 3, 2024 · This is post 2610 in a continuing series of simple ham radio antennas. Many radio amateurs shunt feed their towers as vertical antennas for the lower HF bands (160m-40m). Although the procedure appears clear-cut, there are several factors that must be considered before you convert your tower to a vertical antenna. WebSep 9, 2015 · Dynamic-type sea-water monopole antenna of high efficiency is presented by using a new shunt-excited feeding structure. The shunt-excited feeding structure is mainly formed by a conducting tube and a Gamma-shape (Γ-shape) feeding arm connected to the conducting tube near the top. An equivalent circuit model and ANSYS HFSS software are … t test for dichotomous variables
