This file provides guidelines to build a G3TXQ broad band hexagonal beam R.F. antenna for the six amateur radio bands, 20, 17, 15, 12, 10 and 6 meters. This antenna is featured in the March 2009 edition of QST magazine and is a significant improvement over the Hex-Beam design.
A full-size ( = ½λ) dipole antenna for the 20 mtr band spans about 10 meters (33 ft). Searching for a half-size half-size 2-element Yagi, I found the design by Gary Hanson (KJ5VW), ref. 4. See ref. 5 and 6 for similar designs.
Antennas & Projects 20.1 ANTENNA BASICS very ham needs at least one antenna, and most hams have built one. This chapter, by Chuck Hutchinson, K8CH, covers theory and construction of antennas for most radio amateurs. Here you’ll find simple verticals and dipoles, as well as quad and Yagi projects and other antennas that you can build and use.
antenna works well in horizontal, sloper, and vertical configurations. Observe established safety practices when working with antennas, and avoid proximity to power or utility wires.
The DX Engineering HEXXAGONAL BEAM Mark 2 is a directional beam antenna made with fiberglass spreaders and wire elements that looks like a very large inverted umbrella frame. Even at 22 feet wide and approximately 5 feet tall, it has a smaller turning radius than a two element 20 meter Yagi, and offers several enhanced operating characteristics.
