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 4:1 matches 50(75) ohm unbalanced coax to 200(300) ohm folded dipoles.
