Noise canceler ?

I was looking around online today and I noticed that DX Engineering and MFJ Enterprises makes noise cancelers.

They go between antenna and xcvr.

transceiver ->noise canceler-> antenna and tuner.

Evidently they alter the antenna pattern and blank out noise.

Of course, if the RFI and the signal you want are in the same direction, that is a problem.

How well do they work ? Do they work at all ?

Thanks.

I'll be moving to a rural area in a few months... so it looks like by the time I can buy this, I'll no longer need it.

I have an MFJ-1025. If the second antenna is placed to pick up as much of the noise as possible, they work very well indeed. However, they only null one noise source at a time.

I did the rf choke balun between my xcvr and my antenna mentikoned in the book 'Stealth Antennas'. I can now hear some local hams on various bands.
