It works quite well if you can put up a second antenna that receives the noise you are trying to eliminate. Directionality really has nothing to do with it. If you can receive the noise at an adequate enough level, the MFJ-1026 can be used to null it out by changing the phase of the undesired signal as compared to the desired signal. I published a fairly extensive functional review of the MFJ-1026 attached to a K3, including a live video demonstration here: http://www.worldwidedx.com/product-reviews/110176-mfj-1026-noise-canceling-signal-enhancer-review.html
