Building a 40 meter dipole

WebConclusion: The 20-meter vertical dipole, center-fed with 450-ohm ladder, will be a good-performing and inexpensive 20- through 10-meter omni-directional antenna, used with a tuner and current balun at the tuner. Also useable on 6 and 2, but high radiation angle will limit performance. The line should run horizontal for 40 feet or more. WebMar 2, 2024 · The video is well-organized and covers the building, tuning, and testing of this popular antenna design. Here are a few comments from Greg: video documenting the process of building a dipole. How to build and tune a 40 meter Inverted V wire dipole HF antenna. Here I build a multi-band dipole antenna for HF use on 40-20-15-10-6 meters.

Fan Dipole: 40 Meter and 80 Meter ON THE SQUID

WebA common multiband trap dipole might be one for 80, 40, 20, 15, and 10 Meters. This antenna would require eight traps. Overall, the antenna works pretty good. I've built and used one myself. While the antenna is almost full size on 10 and 15 Meters, the other bands are shortened considerably. The antenna is shortened by almost 12 feet on each side. WebThis shortened easy-to-build vertical, with no-radials, is made from surplus military camouflage poles. It has gain and wave angle comparable to a full-sized ¼λ ground plane antenna with radials .
