Did you see ZTZ's comment that ports A and B have a MW notch? Are you feeding into either of those, and making sure the notch is on? The data sheet mentions that there are selectable notch filters available. Are you using this?

Your LW overload issue is undoubtedly related to how much MW RF you are receiving. As was mentioned earlier, ideally you want to put your filter before, not after, the amp. Otherwise you could risk saturating the filter and rendering it useless.

In your case, at least, I wouldn't even think of using an amplified antenna of any kind. A passive loop - there are many plans for these, and we have a few in our wiki - would be my choice. The selectivity of a passive loop would really knock all those overload issues down a great deal, I'm sure.
