Another popular old school antenna is the multiband fan dipole.
Multiband fan dipole antenna.
Don t worry about the total length of the antenna.
This antenna consist basically of multiple dipole antennas sharing the same coaxial feed line.
The highest frequency antenna is at the bottom and cut for 1 longer than the 1 2 wavelength length in feet 1 01 times 468 divided by the frequency in mhz compared to the construction effort of a standard multi band dipole the only difference is the fabrication of a feed.
Resources listed under fan dipole category belongs to antennas main collection and get reviewed and rated by amateur radio operators.
Considerations adding more dipoles will make the angle at the centre sharper for some the bands the lower wires.
Fan dipole is a multiband wire antenna category is a curation of 18 web resources on wa2hip fan dipoles multiband fan dipole antenna the fence fan dipole.
Multiband fan dipole click for a larger image and more details the image shown above has the 40m linear loaded wire plus 20m 15m wires the overall length of this aerial is 12m.
A pulley for the center is up about 45 feet.
I want to add dipoles for 80m 15m and 10m.
These are going to be the two halves of your dipole antenna.
Just make it as long as possible.
Build this multiband fan dipole for all band hf antenna excitement.
Making it a resonant antenna for all bands from 80m to 6m except warc bands.
This is an effective height for 40 meters and up.
Eantenna multi band wire antennas are cleverly named multi fan dipoles.
Each dipole should be cut for the approximate centers of the bands where you would like it to resonate.
Simply cut two equal lengths of stranded copper wire.
The fan dipole for 40 20 6m performs well.
The multi band fan dipole or multi band parallel dipole provides a very neat solution for an antenna with multiple band capability.
This will affect the radiation pattern.
One separate dipole for each band.
If you have a longer garden you can move the pig tail join further back the return wire.
It works by feeding a group of separate dipoles for each band from a common coaxial feedline.
You can also enjoy multiband performance without traps coils fans or other schemes.
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.
Now it s time to extend the fan with more bands.
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.
Build this multiband fan dipole for all band hf antenna excitement 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.
It also is up high enough for 80 meters for local work.
In the drawing above it is shown for just four bands 80 thru 10.
