RSGB 2018 Convention lecture - VHF Baluns: Fact and Fancy

Ian White, GM3SEK Our ideas about HF baluns have changed dramatically in recent years. The focus today is very much on suppressing unwanted common-mode RF currents, to reduce both the received noise levels and the risks of causing interference on transmit. Now Ian extends those ideas into the VHF-UHF spectrum, taking a critical look at some long-established methods for feeding Yagi antennas and identifying a new list of Do's and Don'ts for modern conditions.
