Some Basics
Hover over the images to enlarge them.
One of the most awarding homebrew projects is making your own antenna. It is easy, you don't need a lot of tools and skills.
Mostly the average DIY tools are perfect for the job.
Tools like wire cutters, screwdrivers, saw, drill, wire, tape are nearly in everybody's toolbox.
Als long as you respect a few rules everyone can make a good antenna for a certain frequency:
- An "Antenna" is the complete antenna system including the coax, switch etc.
- The Antenna must be constructed for the frequency you want to operate on.
- The type of antenna GP, Dipole, Windom, Yagi etc. defines the dimentions of the antenna construction. Dimensions can be found on the internet.
- Use the lowest-loss coax you can afford. Since you will probably be using your feed line for several years and want something that can support your changing interests
As you can see, my constructions aren't always very nice-looking but that isn't very important I can assure you that they work fine.
| Antenna's |
| GP Ground Plane |
To function as a ground plane, the conducting surface must be at least a quarter of the wavelength (λ /4) |

| J-Pole |
The J-Pole antenna is fundamentally an end-fed λ/2-wavelength antenna that uses a λ/4-wavelength long transformer section to supply the feed voltage. |

| Dipole Antenna |
The dipole antenna is a λ/2 wavelength antenna. |

| Coaxial Folded Dipole Antenna |
The Coax Dipole also sometimes called Bazooka is simular to a folded dipole. |
