Twin-lead

WebA balun is a device that converts between an unbalanced signal and a balanced one. For TV wiring, it converts old 300-ohm twin-lead wire to new 75-ohm coaxial wire. If you have existing twin-lead wiring (in good condition) run to your TV, you can just use a balun where the twin-lead ends and a short length of coax to connect it to the TV.

WebAt least once a week we receive a request a for high ratio balun (6:1, 9:1, 12:1) to manage the transition from high impedance ladder line / open wire feedline to coax. This is a common misconception and when using a loop, doublet or double extended Zep (and several others) for multiband operation will result in "operational frustration". WebOct 17, 2024 · Whether or not you can wrap your head around impedance, the point here is that twin-lead wire is much more similar in impedance to the antenna itself. You don’t need a transformer to go from the antenna to the wire. With coax, you do. That’s one more part that was hard to make in the old days, and expensive too. WebBecause the characteristic impedance of twin-lead transmission lines are roughly 300 Ohms, the folded dipole is often used when connecting to this type of line, for optimal … bo jackson acting
