BV6 50 Mhz Yagis

The BV6 50 MHz Yagis resource details the construction of two distinct Yagi antenna designs for the 6-meter band, specifically a 1-wavelength (1wl) model and a 2.1-wavelength (2.1wl) model. The 1wl Yagi, with a boom length of 5.850m, achieves a gain of 9.4 dBd, while the 2.1wl Yagi, spanning 12.90m, boasts a gain of 11.9 dBd. These designs adhere to a proven methodology for optimizing current slope and maintaining constant phase delay across parasitic elements, ensuring high gain per boom length and an excellent pattern. Both designs target a 50-ohm input impedance, facilitating straightforward feeding with a robust folded dipole.

Final verification using NEC-II software confirmed the antennas' exceptional stacking capabilities, yielding stacking gains exceeding 5.8 dB for a 2x2 array with minimal mutual detuning. The resource provides common mechanical data, including boom and element diameters, and specifies element lengths corrected for boom diameter. While the original DUBUS Technik V publication contained incorrect element lengths, this resource provides the accurate dimensions for proper construction, emphasizing the use of readily available materials for cost-effective amateur radio deployment.
