It thought the HyGain Balun is supposed to be a current balun, which to my understanding is just ferrite beads on coax. If this were true, the balun would show no resistance from the center pin of th

The one I saw (and this was about 33 years ago, so I don't remember all the details) was three winding type balun on a piece of ferrite rod about 4 inches or so long and around 1/2 inch diameter. Fro
The BN-86 and BN-4000 baluns are simply a piece of coax with the center going to one attachment point and the shield to the other. It should show infinite resistance between the two attachment points
The BN-86 I had on my old 204BA was a ferrite rod with turns of enameled wire around it. It was a low power version of the BN-4000. The latest BN-4000B data sheet claims it uses coax with type 77 fer
I should have added that the BN-4000B does use teflon coax RGU-303 ? (hard to read the markings - its about the same size as RG-58/U) and 45 ferrite beads. 73, Charles, K4ZRJ ________________________
Not true. The BN-86 is a voltage balun (three windings on a ferrite rod). The BN-4000 is the newer design "current" balun (ferrite beads on coax). 73, ... Joe, W4TV _________________________________
For some reason, I thought this was true too, but I was mistakenly confusing BN-86 with a Telrex balun. The BN-86 is as Joe describes. 73, Joe K2XX _______________________________________________ ___
