Rob Conklin N4WGY delivered an informative presentation on Hexagonal Beam antennas (Hex Beams), detailing their construction, performance, and benefits over traditional multiband Yagi antennas. He highlighted their cost-effectiveness, lower wind loading, lightweight design, and multi-band capabilities without requiring traps. Conklin also discussed the improved G3TXQ design, which offers better SWR performance across ham bands. The presentation included practical construction tips, resource recommendations, and demonstrations of performance analysis tools, making it a valuable resource for both novice and experienced antenna builders.

The multiband tuned doublet, or center-fed Zepp, is a simple and efficient HF antenna that operates effectively across most amateur bands using a balanced parallel-wire feedline and antenna tuner. Unlike coax-fed dipoles, it tolerates impedance mismatches with minimal loss. By selecting suitable feedline and dipole lengths, one can achieve stable multi-band operation. While it doesn’t match monoband Yagis, it offers excellent performance, low cost, and broad coverage. Its radiation pattern and efficiency vary with frequency, but it remains a practical and versatile solution for HF operators.
