The RT-5000 system frequency range is 29.7 - 400 MHz (AM), 29.7 - 960 MHz (FM). However to use the maximum frequency range, you must have an appropriate antenna for the system. The antenna used with the system determines the possible frequency range of the RT-5000.

Antennas such as the AT-550, AT-560 and AT-5000, coupled with the appropriate tuner, will reach the full span of the frequencies offered by the RT-5000. The downside of purchasing an antenna for the full frequency range is the high cost involved; an antenna system such as the ones mentioned above, cost as much as $10,000 new condition. Otherwise it is recommended that you purchase and install antenna(s) designed for your desired frequency range.
