Please click link to read the full article. Comment: Thanks to Igor Grigorov (VA3ZNW) for this wonderful idea for a small, easy-to-tune 20-meter helical antenna which can be used on all amateur radio bands from 40 meters to 10 meters with an antenna "tuner." Igor says this reduced size HF antenna works well, considering its dimensions. The antenna is also "stealthy" and won't attract the attention of neighbors. The article provides a good step-by-step tutorial on how to design, build, and use this antenna. Igor's article contains several well thought-out steps: Materials The importance of grounding and ground radial systems Tuning and adjusting the antenna Schematics and diagrams of the antenna Antenna "tuner" requirements For the latest Amateur Radio news
