Learn how to build a fan dipole antenna for all HF bands using a new method based on Stanford Research Institute research. See construction tips, photos, and feedback from other ham radio operators.
8 mar 2022 · Learn the difference between the original fan dipole, a wideband antenna that covers the entire HF spectrum, and the modern fan dipole, a multiple half-wave dipole on a common feedpoint. See the SWR curves, derivation, and alternate versions of the fan dipole.
26 sty 2022 · Learn how to build or buy a fan dipole antenna, a multiband version of the popular dipole that can cover several HF bands with one feedline. Find out how it works, how to tune it, and what are the advantages and disadvantages of this antenna type.
A fan dipole consists of individual monoband dipoles that are combined on a common balun. The dipole wires are arranged one below the other and kept at a constant distance with spreaders. The longest (top) dipole is braced, it carries the dipoles hanging below it.
12 mar 2022 · Learn how to build a simple and effective fan/parallel dipole antenna for amateur radio on 40 and 20 meters. See the design, construction, measurement and performance of this antenna with a balun and coaxial cable.
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 fan dipole. The web page explains the advantages and disadvantages of each method, and provides examples and references.
Multiband antenna #5 - the "fan" dipole. This is really just the simple dipole but a bunch of them, all using the same center insulator and feed line. Yes, you just cut wire dipoles for each band you wish to operate (40 and 15 can use the same one), attach them all to the center insulator and feed line and scurry from band to band with ease.
