CQ April 1994 pp. 26-46, More On The 1:1 Balun BY JERRY SEVICK*, W2FMI Citat: "...Baluns have taken on a more significant role in the past few decades with the advent of solid-state transceivers and Class B linear amplifiers, which have unbalanced outputs...R. Turrin, W2IMU — 1964. The first presentation in the amateur radio literature on 1:1 baluns using ferrite cores was by Turrin in 1964.10 Turrin, who was a colleague of Ruthroff at Bell Labs...", backup

pacarc.org: Antenna & Transmatch Evaluation Field Manual. Official Guide for the Strange Antenna Challenge Citat: "...Baluns are actually a small family of devices: balun, balbal, or unun. These all refer to the whether you desire to move between balanced (ladder line) to unbalanced (coax) transmission line (bal-un), between balanced and balanced line (bal-bal), or between unbalanced and unbalanced line (un-un). I will usually refer to all of these with the generic term “balun.”...The most common baluns are 1:1 (one to one) and 4:1. Baluns are a form of transformer, either changing voltage or current by a given ratio...Properly terminating balanced line is important...You may also place a “bal-bal” at the antenna feedpoint. This will adjust the impedance...Connecting your balanced line to a single coax transmission line will require a balun...", backup
