Short multiband hf antenna. Enter the fan dipole: a time-tested, efficient, and surprisingly straightforward solution. Here you can find a construction manual for an end fed multiband antenna which covers the shortwave bands from 80 -10 meters corresponding to 3,5 Mhz to 29 Mhz. harmonic resonances. BUILD THIS MULTIBAND FAN DIPOLE FOR ALL BAND HF ANTENNA EXCITEMENT (NEW UPDATED CONSTRUCTION TIPS FOR FASTER TUNING---SEE BELOW) CONSTRUCTION UPDATES FOR EASIER TUNING WITH ADDITIONAL BUILDER FEEDBACK Based on research done by the Stanford Research Institute (SRI) to construct a three-frequency multi-band dipole that would work without any need for cut and try techniques, we pass on this Explore multiband antenna designs. Even though it is a "compromise" antenna, it has good overall performance on most hf ham bands when used with an external tuner, and allows coax as an entry feedline to the radio equipment eliminating the need and hassle of ladder line or twinlead. Two or more dipole antennas a connected to a common feedline. The original fan dipole and related antennas modify the shape of the elements to cover a wide frequency range, like 5 to 30 MHz or more, with a reasonably low SWR. Contains the optional "R2" radial for operation on 80m SSB. tuned antennas (“doublet”) A “doublet” is a generic term for a dipole that is fed with low loss cable (typically parallel-conductor twinlead or open wire line with impedances of 300 – 600 ohms) and matched on multiple bands using an antenna tuner at the junction between the parallel-conductor line and the coax. Another good choice is Hustler HF antennas, the price is lower than the Super Antenna. bnd vsnxqp gdxabgk gnkdc bbbhg luopld kej xkopal ohltg pwrqs
