5 maj 2023 · multiband dipoles. last updated 5 May 2023. The half-wave dipole is primarily a monoband antenna, since it is one-half wavelength long at only one frequency. But because it is such a simple and effective antenna for many HF applications, several different methods have been developed to use a single dipole antenna on 2 or more bands.
CONSTRUCTING THE MULTIBAND DIPOLE: (Older cut and try method) 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.
classic multiband dipole antenna. Power is fed at the center through a length of 450-ohm windowed ladder line. The ladder line connects to a balun that converts the impedance to a lower value for the antenna tuner. Finally, the tuner connects to the transceiver. ARRL1989 1
12 mar 2022 · After some research, and wanting only one antenna connection for my Kenwood TS-2000 radio, I settled on a fan/parallel dipole antenna. It's very simple to build, and really hard to beat the performance of resonant dipoles.
8 kwi 2018 · Five best homebrew fan dipole antenna projects easy to build. The fan dipole antenna is a simple wire antenna consisting of multible monoband dipoles sharing a single coax feed line.
for multiband coverage and physical short- ening. This antenna covers 65 kHz of 160 meters, 75 kHz of 80 meters and the entire 40-meter band with SWRs under 2:1. The bandwidth limitations on 160 and 80 meters can be largely offset with an antenna tuner.
My Homemade Multiband HF Fan Dipole Antenna. by Robert Ewers K9HOU. (Spring, Texas, U.S.A.) Fan dipole hoisted up its mast. My stacked dipole worked great on 10, 15 & 20 meters but when I tried adding a 40-meter element, it was too big. (See reference at the end of this article)
