Using my repaired mfj 266 analyzer i am getting grate swr readings on 40 20 10.
40 20 10 meter fan dipole attic antenna by kd2goe. The fan dipole for 40 20 6m performs well. Eantenna multi band wire antennas are cleverly named multi fan dipoles. A indoor magnetic loop antenna that covers 20 17 15 12 and 10 meters band with a 3 meter lenght of 22 mm copper tube by g4izh indoor multiband dipole this indoor dipole is available in two version for 20 10 meters and 40 10 meters. I added fans for 20 and 10 meters using the mfj 259b to measure and cut.
Now it s time to extend the fan with more bands. Then i combined my 40 20 10 meter antenna with a w2au balun that was part of my 10 meter antenna. Eznec data files available by hb9mtn. So far i am tanning around the bands and it is grate.
December 14 2014 in. A variety of models are available including 80 40 20 15 and 10 meters or 40 20 15 and 10 meters a 20 15 and 10 meter model a two band model for 80 and 40 meters and a special 30 17 12 and 6 meter model. Considerations adding more dipoles will make the angle at the centre sharper for some the bands the lower wires. These are the parallel wire type of multi band dipole kits with special spacers to keep the different dipoles separated all connected to a common feedpoint and 1 5 kw pep balun.
Making it a resonant antenna for all bands from 80m to 6m except warc bands. I do not recommend this unless you do not happen to have blown fiberglass insulation in your attic. I want to add dipoles for 80m 15m and 10m. This will affect the radiation pattern.
