You didn't say what kind of antenna it was. If it was on of the wind up
portable wires, that's the problem. It will work fine for shortwave but for
medium wave (AM) it is way to short. It will make reception worse.

Hello,

I'm hoping someone can help. I have a DX 398 and just picked up an
external
antenna and AM reception is worse with the antenna plugged into the
external
antenna jack. How could this be ? Even on local AM stations the
reception
almost disappears, why would this happen ? I am in a spot where AM
reception is really bad but shouldn't it improve with the external
antenna,
not get worse.

If any one could help I would appreciate it.

thanks.

Jason
