I need to build a good current balun for 80 and 160 meters. Palomar has 43 material that has a .5 inch hole that 9913f coax will fit through. These beads are 1.12 inches long. How many of these will I need to put over the coax to make an effective balun? Another question on the same line. Several years ago I saw either in a mag or handbook where a current balun was made out of steel wool placed over the coax. The steel wool was compressed inside a plastic tube with the coax run through the middle. As these ferrite beads are expensive (I am a cheap skate) has anyone used the steel wool for a balun and did it work? If this will work how long does the tube stuffed with steel wool have to be? I know there is a few fellows out there laughing at this question. But I just have to ask.
