I have a problem with RF on 40m and below getting into my speaker and 
mic lines. In both cases, beads solved the issue. Then I discovered that 
a choke clamped over the coax near the antenna helped. Turned out I was  
incorrectly matching my unbalanced coak to my antenna. The result was RF 
coming back over the  coax shield.
