Building a Fan Dipole With NØVCU

#hamradio #dipole #antenna A dipole is the go-to antenna for many hams, but why is it so popular? Beacause it’s an inexpensive, yet effective antenna you can build yourself using wire, insulators and rope that you may already have in your junk box. Plus, you’re not just limited to one band. You can enjoy the benefits of multiple dipoles on different frequencies, connected at a single point, and use only one feedline. These multiband antenna combos are commonly known as fan or parallel dipoles. How it Works The way in which HF multiband parallel/fan dipoles operate is each dipole presents a low impedance at the feedpoint on its resonant frequency. As the signal frequency moves away from the resonant frequency of one dipole, its impedance increases and it does not radiate power. But at the resonant frequency of another dipole, the impedance drops and it will take power at the feedpoint. Each element will radiate as a resonant dipole on its own frequency, making this an easy way to provide multiband capability on a number of different HF bands. In the figure below, the first element is tuned for 40 meters, the second for 20 meters, and the third for 10 meters. You get three bands in the space occupied by a single-band antenna. - From OnAllBands.com I'm an Amateur Radio enthusiast. I love the hobby and experimenting with radios, antennas and software. I have a lot of fun. On my YouTube channel I upload videos mostly on the Icom 7300 and Icom 7610 as well as Ham Radio software programs. I hope to inspire people to get involved in Amateur Radio. ○○○ LINKS ○○○ Gas Buddy ► https://pay.gasbuddy.com/?pid=referra...
