 I have a Marantz 2216B receiver set up in my office to tune in some AM stations while I am working. I am located on the tenth floor of a building downtown. The Marantz's ferrite antenna works so-so; one problem being that I can't extend it out all the way out from the receiver because the shelf is not wide enough in back of the unit. The receiver picks up some noise and grunge along with the AM signal. Is there an antenna that would work better. The unit has a separate terminal to connect an external AM antenna.

 The Godar DXR- 100 works great indoors for me.

 Too much RF interference everywhere. All receivers are notorius for having pitiful AM performance.

I tote a battery powered GE Super Radio around the house and yard if I just have to listen to AM.

I'm just sayin'.

 That External AM connection is simply for a single length of wire, the longer the better; that additional wire may not be any better due to the building itself but there is no harm in a trial. Also, why not just remove the ferrite antenna from its' holder so that you CAN align it with desired stations? It can rest on top of the receiver with no ill effect.

 A longish piece of wire and try a few arrangements of the run of the wire until it's good enough on most desired stations, noting that the final tuning of each AM station will require a different positioning of the ferrite rod the Marantz came with.

If these approaches don't work out, then get one of Crane's tunable passive AM loops - the one that connects to yr receiver's AM/antenna posts, ie to the ground post as well as the AM one.

Lastly, indoor is what you are stuck with, and isn't ideal.

 I repositioned the unit in front of a window and the ferrite antenna can move around. The unit sounds a lot better. I think I am going to leave as is for now. I did notice that you can't remove the ferrite antenna from the back of the Marantz.

It would be worth trying..., posted on October 4, 2009 at 13:51:04

 ...a larger wire loop. A single wire attached to your AM terminal will pick up more interference than stations, but a loop tends to null out/ignore a lot of static and noise interference.

1/ Take however much insulated wire that's needed and form it in a loop around the window frame.

2/ Join the two ends of the wire together electrically (strip & twist) to form an electrical loop.

3/ Form one or two small loops in the wire of the big loop and slide them over one end of your ferrite antenna. Try it out.

This has worked very well for me in many situations, and not so well in a few.

But I suggest it's worth a try.
