Homebrew Multiband Fan Dipole Antenna

Just make it as long as possible.

Homebrew multiband fan dipole antenna.

These are going to be the two halves of your dipole antenna. If you have a longer garden you can move the pig tail join further back the return wire. For further information on the 40 and 15 meter multiband antenna please see my other article the 40 and 15 meter dipole a myth exposed. These dipoles are used for many radio communications applications and can provide a very neat and easy to implement solution for a multi band dipole.

But the interaction between each element made it also difficult to tune. I started with 10cm between each dipole. In the case of my 40 15 fan dipole you need 30 degree angle separation to get good performance. You won t be trimming or adding wire to this dipole.

Theory and construction of a novel trapless center loaded off center fed cl ocf dipole or windom antenna for the 80 40 30 20 15 and 10m hf amateur radio bands h pole multiband antenna hb9mtn. Don t worry about the total length of the antenna. The fan dipole antenna also known as parallel dipole antenna or fanned dipole antenna is a multi band wire antenna tha can be very easy to build. You can also enjoy multiband performance without traps coils fans or other schemes.

The next antenna built was a so called fan dipole antenna. The image shown above has the 40m linear loaded wire plus 20m 15m wires the overall length of this aerial is 12m. The multi band fan dipole or multi band parallel dipole provides a very neat solution for an antenna with multiple band capability. Build this multiband fan dipole for all band hf antenna excitement.

One separate dipole for each band. Multiband fan dipole click for a larger image and more details. In the drawing above it is shown for just four bands 80 thru 10. Build an hf ham radio dipole antenna it is easy to build construct and erect a dipole antenna for the hf bands.

Each dipole should be cut for the approximate centers of the bands where you would like it to resonate. The swr is less than 1 2 1 all the way across the 15 meter band with independent adjustment for 40 meters. I figured out that i needed at least 15 cm between each element the more the better. 160 80 40 20 15 10 metres etc using a few simple components at a minimal cost and get great results.

5 wires parallel for each band fed by a balun at the common center. Simply cut two equal lengths of stranded copper wire.
