Don Keith, N4KC, shares his opinions on the best multiband antennas for Amateur Radio, such as the G5RV, the fan dipole, and the inverted V. He explains the pros and cons of each antenna and how to optimize them for different bands.
5 maj 2023 · Learn how to use a single dipole antenna on multiple HF bands using different methods, such as harmonic resonances, multiple dipoles, tuned antennas, and more. See examples, diagrams, and tips for each method.
W5GI Mystery Antenna is a multi-band wire antenna that performs exceptionally well even though it confounds antenna modeling software. This antenna covers 80 to 6 meters with low feed point impedance and will work with most radios, with or without an antenna tuner.
14 maj 2016 · A selection of five easy and easy to build HF multiband wire antennas.
Here is a fairly simple and easy to build multi band horizontal fan type dipole that can be constructed for all band operation from 160 meters up thru 6 meters or even higher. In the drawing above, it is shown for just four bands, 80 thru 10. One separate dipole for each band needed.
10 mar 2020 · Because of the low losses at high SWR, you can use the doublet as a multi-band antenna. As a portable antenna, it’s hard to beat, especially as an inverted vee. Use a tree branch or telescopic pole to hoist up the center, tie off the ends, and you’re in business.
27 cze 2012 · The interaction between the radiating section and the feed-stub makes the G5RV usually easy to match on all-bands from 80 through 10 meters with an ordinary low-cost antenna tuner. In spite of small size, it provides "almost" dipole equivalent coverage on 80 and 40 meters.
