This antenna is based on the 80/40M trap dipole design found in the ARRL Handbook. The W2AU balun is used with a pair of 40M traps to create a multiband dipole antenna capable of operating on 80, 40, 20, 15 and 10 meters. It is approximately 110 feet in length and provides a relatively low SWR on these bands.

long the standard of the industry the W2AU baluns are built to last!
The W2AU is the preferred Balun of Amateurs worldwide. W2AU’s operate at a low VSWR from 1.8 to 40 mHz, and handle powers up to 2 KW PEP (at SWRs of less than 3:1). W2AU Baluns are transformer designs with ferrite cores to provide 95% minimum coupling efficiency. Each has a built-in lightning arrestor, hang up hook, and 600 lbs of pull-apart strength in a weatherized, rugged package using only stainless steel hardware and quality materials. Two models are available. The 1:1 matches 50(75) ohms unbalanced coax to 50(75) balanced dipoles. The 4:1 matches 50(75) ohm unbalanced coax to 200(300) ohm folded dipoles.

these Baluns can be used on beams and quads!
For matching yagi or quad elements select the Beam models of the famous W2AU or W2DU Baluns. These models are designed to be mounted horizontally to a beam’s boom. Pigtail wires are provided in lieu of the hooks on the wire models to connect these Baluns to the driven element. Specs for beam models are the same as their respective wire models with the exception that the W2AU and W2DU HF beam models only operate from 40 to 10 meters.
