Here what you ight consider doing;
The additional wire should, hopefully, increase the signal you capture. If you have window close to where you listen to your radio, stretch the wire around the room , at the highest level you can INDOORS. I use cup hooks to supend the wire. This will improve the shortwave signals. To improve the MW signals in the AM band, do some researach at some of the Yahoo groups on MW natennas and it has much more infor mation than I can list here. The 1103 is good portable, but DO NOT hook it up to an outside atenna. It will overload and you will get false signals everywhere. A good loop antenna or a Select-Tenna will improve the MW section. Hope this helps. Email me if you have questions. KE5LDO.
