Antenna Feedline Optimal Length for Resonance

Updated 4-18-2024 I recently discovered a YouTube video that shows how to cut an antenna’s feedline length to achieve resonance (See below).

Whether it is actually optimized or not is somewhat irrelevant although it is known that our task will optimize the antenna for its 40 meter band. Our task to to see if we can shift the… Read more »
