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.

With the source impedance matched to the line, the reflections coming back towards the driver get absorbed and not re-reflected … chuskit goes to school summaryWitryna22 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 … chuskit goes to school pdfWitrynaWith this balun type, impedance transform of ratio 4:1 can be achieved. The length of balun section of this coaxial cable is expressed as follows, L (feet) = 492*V/F (MHz), where V is velocity factor of the coaxial cable. Matching stubs: The shorted stub can be constructed which can produce reactance of any value. df power investment holdingsWitrynaBetween 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. Between P2 and P3 is a resistor that's twice the characteristic impedance. chuskit school chali
