WebNow drill the four fastening holes with a 3.5 mm drill. In addition to the coax connector, drill a 5 mm hole for the countercapacity connection. Once this is done, we’ll turn the box over. Now we continue with the marking and drilling of the holes for the long wire antenna connection and the strain relief. WebA balun's purpose is to allow connecting a balanced, (e.g., a dipole or driven element) to an unbalanced line such as coax which is not balanced, thus the name, Balun. The 1:1 choke "balun" is not actually a balun. It's function is to help eliminate rf currents from flowing on the outside of coaxial cable using the principle of choke action.
Web22 feb. 2024 · A 1 : 1 balun can be used to match a coax to an equal value impedance, balanced line. A simple choke (one to eliminate common mode currents - CMCS) can be made by winding 25 feet of coax around a one gallon ice cream container. They have a slight taper, making it easy to remove the coil after winding and securing with wire ties in … WebShow diagrams, winding methods and tables of some 1:1 and 4:1 baluns for 1.8 - 30 MHz suitable for use up to 200W (400W peak) on systems using 50 or 75 ohm coaxial cable input where SWR should not exceed 1.6:1.
