The tool is named after its inventor, Les Moxon (G6XN). . The 2-Element-HB9CV-Beam The HB9CV-Beam is a 2-Element-Yagi with two driven elements and was introduced by Rudolf Baumgartner, HB9CV in the 1950ies. Having a hard time finding any info for a 2 element yagi for 11 meters. The more parasitic director elements (up to a point) added will increase the DB (gain) and narrow the receptive beam width. It's used to design a Moxon Rectangle or a 2-element Yagi-Uda antenna, which can greatly improve both reception and transmission capabilities on the 20-meter band. It was installed on a short mast about 15 to 17 feet high with a rotor on the ground. For fine-tuning, use modeling tools or The Yagi antenna is a directional antenna using parasitic director and reflector elements to amplify the radio frequency signals from the direction it is pointing. Shorter antennas, particularly the 2-element designs, may be supported from a cross spreader on top of a single mast, and rotated by untying and moving the bottoms of the ropes. 73, Keith WB2VUO Editor's note: Many years ago, the 10 meter version of this 2 element Yagi was built by myself using much the same construction techniques as mentioned in the article using small aluminum tubing.
