Jim, I made a braid breaker by using a binocular core 73-202 with 2 turns primairy and 2 turns on secondary . The term braid breaker comes from John s latest edition of low band DX ing
I found that it is difficult to get signal levels identical on both elements when using it, so maybe better to use a good common mode choke at the feedpoint .

It DOES make sense to decouple the feedline. I've never heard of a "braid breaker." Under NO conditions should you open the shield == that prevents the shield from being a shield. The good ways to decouple the feedline are 1) a good transformer, a good common mode choke, and radials. See Chapter 8 of http://k9yc.com/RFI-Ham.pdf for winding guidelines for the choke. 73, Jim K9YC _________________ Topband Reflector Archives - http://www.contesting.com/_topband _________________ Topband Reflector Archives - http://www.contesting.com/_topband
