There is a "noise canceller" made and sold by TimeWave that works extremely well for 
repetitive type noises, like power-line crap. It won't do much for random junk though.

MFJ makes one too, but from the videos I have seen of it working on youtube, it is somewhat 
"iffy".

Both work on a phasing principle and both need an external "noise" antenna.
