WebAntenna Theory - Baluns. A Balun is used to "balance" unbalanced systems - i.e. those where power flows from an unbalanced line to a balanced line (hence, balun derives from bal ance to un balanced). As an example, consider a coaxial cable connected to a half-wave dipole antenna shown in Figure 1. Figure 1. WebThe antenna impedance matching components (BOX “Z” above) to match the antenna impedance to the coax line impedance (usually 50 ohms). For non-resonant end fed antennas, the typical feed point impedance is 300 to 600 ohms and a 9:1 impedance transformer (e.g. 450 ohm average antenna impedance to 50 ohm coax, also know as a … hank williams sings gathering flowersWebFind many great new & used options and get the best deals for High Quality Balun One Nine Tiny Low-Cost 1:9 HF Antenna RTL-SDR 28d DET at the best online prices at eBay! ...
