Witryna22 kwi 2015 · It's fairly simple to choose a point where the impedance is 50 -j something ohms. Then to match the antenna, only a series inductor is required. Please excuse … WitrynaThere's nothing wrong with using 75 ohm coax in particular. It's just that it is conventional for amateur radio equipment to be designed with 50 ohms characteristic impedance, so if you substitute 75 ohm coax without doing anything else you will have mismatches.

In electronics, impedance matching is the practice of designing or adjusting the input impedance or output impedance of an electrical device for a desired value. Often, the desired value is selected to maximize power transfer or minimize signal reflection. For example, impedance matching typically is used … Zobacz więcej Impedance is the opposition by a system to the flow of energy from a source. For constant signals, this impedance can also be constant. For varying signals, it usually changes with frequency. The energy involved can be Zobacz więcej Adjusting the source impedance or the load impedance, in general, is called "impedance matching". There are three ways to … Zobacz więcej In RF connections, impedance matching is desirable, because otherwise reflections may be created at the end of the mismatched transmission line. The reflection may cause frequency-dependent loss. In electrical … Zobacz więcej Acoustics Similar to electrical transmission lines, an impedance matching problem exists when transferring sound energy from one medium to another. If the acoustic impedance of the two media are very different most … Zobacz więcej Whenever a source of power with a fixed output impedance such as an electric signal source, a radio transmitter or a mechanical sound (e.g., a loudspeaker) operates into a load, the maximum possible power is delivered to the load when the impedance of the load ( Zobacz więcej Power factor correction devices are intended to cancel the reactive and nonlinear characteristics of a load at the end of a power line. This causes the load seen by the … Zobacz więcej Telephone systems Telephone systems also use matched impedances to minimise echo on long-distance lines. This is related to transmission … Zobacz więcej

The typical co-phasing harness for two CB antennas is a crude 2-way power divider with roughly 50 ohms impedance at the radio connector and at both antenna connectors. This is because the length of the 75 ohm cable used is very specific and critical to maintain a 50 ohm match throughout the system. bird leg band identificationWitrynaBetween P1 and P2, and also between P1 and P3, are quarter-wavelength transmission lines having an impedance of $\sqrt 2 \cdot Z_0$. For your case that works out to $\sqrt 2 \cdot 50 \Omega = 70.7\Omega $. 75 ohm coax is close enough and easier to find.
