The supplied FM antenna, though basic, should provide better reception in cases where the internal antenna does not suffice. Remember to change the rear antenna switch from internal to external when using an external antenna.
For optimal performance, place the radio and/or antenna near a window or outside wall. Make sure the power cord and antenna are not bundled together or near each other.
Other than the above, there are a few options for improving reception.
First, a word about AM, FM, and reception: Although FM stereo provides higher fidelity than AM, its signal has a shorter range and is susceptible to multipath.
Multipath occurs when an FM signal is reflected off nearby structures. These reflections create multiple signals which arrive at your radio at slightly different times. This results in hiss, noise, and in some cases, a reduction of the overall signal strength. Multipath is caused by buildings, hills, bridges and anything else that may obstruct the FM signal from reaching your radio.
AM uses a simple, mono, long-range signal, but it suffers from poor fidelity, static, and is susceptible to inclement weather. Some AM stations may come in clearer at night when their signals bounce off the earth's ionosphere and travel long distances. Other AM stations received during the day time may not be received at all at night because the Federal Communications Commission requires many AM stations to operate at reduced power at night or cease broadcasting all together so as not to interfere with other AM stations' signals.
For improved AM reception, we recommend an indoor wireless AM antenna. If a more powerful antenna is necessary, you can try an FM dipole antenna or amplified indoor antenna, but the best FM reception is often obtained with an outdoor antenna specifically designed for FM.
Splitting your cable TV wire and connecting it to the rear external antenna jack on your radio may not automatically improve reception. Most cable companies require you to call them to activate this service and some charge a monthly fee.
Please note that even the most sensitive tuners cannot receive a signal that isn't there. If you're attempting to receive a station's signal that doesn't reach your listening area, no tuner or antenna will help.
