Yagi Antenna Projects and Information
Resources for building Yagi-Uda antennas, including designs and construction plans for various bands.
Yagi antennas are a popular choice for hams seeking directional gain, especially on VHF, UHF, and the higher HF bands. Their design allows operators to focus RF energy in a specific direction, improving signal strength for DX contacts and reducing interference from other stations. Many hams enjoy building their own Yagis, experimenting with element spacing and boom length to optimize performance for specific frequency ranges.
This category offers a wealth of resources for Yagi antenna projects, from simple portable designs for fox hunting to complex multi-element arrays for serious contest operation. You'll find detailed plans for single-band Yagis, including 6-meter designs like the EF0610, and multi-band options such as the DK7ZB triband VHF Yagi. There are also articles explaining Yagi-Uda antenna theory and construction techniques, helping hams understand how to achieve maximum gain and front-to-back ratio for their homebrew antennas.

While calculations are provided for a 146 MHz design, adjustments are necessary for different frequencies. Safety precautions and potential result variations are emphasized. -

This project introduces the Loggi, a hybrid antenna merging the wide frequency coverage of log-periodic dipole arrays (LPDA) with the high gain and front-to-back ratio (F/B) of Yagi antennas. Traditional LPDAs span broad frequencies with moderate gain and low VSWR, while Yagis provide high gain and F/B over narrow bands. By analyzing high-Tau LPDA designs, it was found they could nearly match the gain of VHF/UHF Yagis while maintaining excellent patterns, F/B, and front-to-rear ratios (F/R). Optimizing specific elements for target frequencies (e.g., 144.1 MHz) led to the Loggi, which uniquely features all driven elements without passive directors or reflectors. This design effectively functions as a narrowband optimized LPDA, with front elements acting like Yagi directors and rear elements like Yagi reflectors, thus enhancing gain and directional characteristics while retaining broad frequency versatility. -

A cost-effective alternative to the Optibeam OB10-3W, a high-performance but expensive tri-band Yagi antenna for the 20, 17, and 15-meter bands. The original Optibeam, featuring three full-size elements on each band, delivers strong forward gain and front-to-back ratio but comes with a high price tag. To address this, a custom design was developed, offering similar performance at a fraction of the cost. Using accessible materials and a simple 1:1 current balun, the homemade version proved highly effective, making it a practical solution. -
