Dipole Antenna Projects and Designs
Construction guides and plans for monoband, multiband, shortened, and vertical dipole antennas.
The dipole antenna is a fundamental building block for many ham radio stations, known for its simplicity and reliable performance across HF and VHF bands. Operators often choose dipoles for their ease of construction and adaptability, making them popular for both permanent installations and portable operations. Many hams start their antenna projects with a basic dipole, learning about impedance, SWR, and propagation in a practical way.
This category offers numerous designs for building and optimizing dipole antennas. You will find detailed guides for multiband dipoles, like the N3UJJ project, which eliminate the need for an antenna tuner, and shortened designs such as the W5VMs Shorty 40 for limited spaces. There are also resources covering specific construction techniques, including trap dipoles for WARC bands and innovative feeding methods like LA6PB's split dipole, helping hams achieve effective QSOs on their preferred frequencies.

The Linked Dipole is a multiband antenna designed for 80/60/40/30/20m bands, optimized for the (tr)uSDX low bands configuration. It incorporates a 1:1 Balun to prevent common mode currents, ensuring balanced operation with coaxial cable. The Balun, wound on an FT140-43 core, achieves 37-40dB attenuation. The design includes a 3D-printable housing for compactness and waterproofing, with labeled link insulators for ease of use. Wire lengths were meticulously adjusted for optimal performance with a 7m pole and 3m rope extension, ensuring the antenna's ends are off the ground for improved behavior. The project includes downloadable printables for DIY construction. -
