Simple Ham Radio Antennas. Antennas without "tuners". Part 2. Post #255

One of the more popular amateur radio antennas is the multiband "Fan Dipole" and its close relative the multiband inverted vee "Fan Dipole."  According to Howard (W6HDG), the Fan Dipole "consists of  two or more distinct half wave dipoles which are mounted to a common parallel feed point so that a single feed line can be utilized."  With a little ingenuity and careful trimming, it is possible to make a single band dipole antenna work on several bands just by adding half wavelength dipoles for your favorite band to the center coax connector and by "fanning them out" below the dipole for the lowest frequency.  Add a 1:1 balun or a "choke" balun below the center connector, connect some 50 ohm coaxial cable, run the cable to your rig, and you're ready to go on your favorite bands without a "tuner" and a ground radial system. According to Simone (IW5EDI), "an antenna like this works on multiple bands because the antenna
