The 40-20M-3-5 is a coil loaded 40 meter 3 element Yagi interlaced with a 20M 5 element Yagi. This antenna is the perfect package to bust the sun spot cycle. As the upper HF bands go quiet the lower bands will be the best for DX.
Mechanically all the elements are mounted between 1/2” thick, machined aluminum clamp plates! The Driven elementsare split and insulated with solid fiberglass rods and fed with a weather sealed 1:1 baluns.
All the 40M elements use aUV protected covered air dielectric loading coil. The coil is made from 3/16″ aluminum rod to reduce loss and keep the Q high, that reduces the overall element length, wind load, and turning radius. At the center of each 40M element a vertical riser and non-metallic Philistran element support cord helps reduce mechanical stress, and element droop. The result is a powerful package of clean mechanical design, quality materials, and outstanding performance. When choosing an antenna compare customer support, performance, construction and durability…. You will find M2 is the choice and “The Cycle Buster” is NOT just another Yagi!!
