VDA Antenna for 30m ^new - This project documents the construction and enhancement of a 30m Vertical Dipole Array (VDA) antenna inspired by Remco 7QNL article. Initial design utilized an 18m Spiderbeam pole and a 4m boom. Improvements included a lighter boom structure using fishing rods and a revised coaxial arrangement for enhanced mechanical stability.

Understanding the Hexbeam Antenna - The Hexbeam is a great little antenna! It should be high on your list of options if you want a design that can be multi-banded, exhibits useful gain and directivity, is very lightweight, has a small turning radius, and which lends itself readily to Do It Yourself construction.

Moxon Mania - Building the Ultimate 4-Band Moxon Antenna - The article details the design and construction of a four-band Moxon beam by a radio amateur. The beam, mounted atop a rooftop tower, aimed for gain over a dipole on 20 meters, cost under $500, and included additional bands. The design features fiberglass spreaders, four bands (20/15/10/6 meters), and a single feedpoint. The construction involved computer modeling, NEC source code, and specific dimensions. The article outlines the assembly, materials, and tuning process, including in-situ adjustments for optimal performance. Despite initial challenges, the beam improved signal strength and facilitated contacts on multiple bands, marking it as the best HF antenna the author has owned.
