I recently built an OCF dipole using a W2AU 4:1 balun. It seems to be working very well especially on 40 and 80 meters but I don't know much about the balun. I'm a little concerned about the power ha

There are a lot of options for OCF chokes/baluns that are arguably better than the W2AU model. For starters, check out the web site of G3TXQ and also the web site of DJ0IP. There is a lot of info the

It's disturbing to me to see my late friend Walt Maxwell, W2DU, disparaged this way. Walt addressed this issue before his passing here: http://www.eham.net/reviews/detail/2300 Wes N7WS On 3/15/2017 5

Wes, I think you may be confusing W2AU-branded parts with W2DU's. Walt's original common mode choke design paper was excellent -- as I'm sure you know, he built and tested units with 50, 100, and 200

Interesting reading, I was not aware of this. I guess he should have patented the idea. It is pretty sad (fraudulent?) that manufactures call something a W2DU balun when it really is not. John KK9A I

W2DU is an active callsign. It would seem that removing W2DU references from the 3 or 4 companies referring to that design could quickly be told to quit it by the current holder of the callsign W2DU.

This company produces total crap. I bought several center insulators from them about five years ago. Both of the two that I used fell apart, and with only modest stress on them. 73, Jim K9YC On Thu,3

Thanks to all who commented on my question about W2AU baluns. Very informative! I think I'll take a look at Balun designs and Hy-Power antenna co. And see what I can come up with. 73, Jeff N0OST ____
