Both.

 

Here is a good technical read on the MFJ-1025

You need two antennas

 

I just used a magmount cb antenna for #2. Worked very well.

 

Didn't Moleculo do a review on this? I can't seem to find it. Maybe it was a review he did for cbradio magazine? It's out there somewhere.

 

Hey, Shade. The link I posted above has a good review as well

 

Found it.

 

It works great for man made noise. JPS made a unit called ANC-4, then Timewave bought them out. That's the one I had. I imagine the MFJ unit works the same. The important thing is to be patient. Depending on the noise source, it can take a great deal of experimentation getting it to work. Follow the directions carefully.

They do little to alleviate atmospheric noise, though.
