BAD,

"The Sony AN-1 Active Antenna provides good reception
over the range .15 to 30 MHz."
http://www.universal-radio.com/catalog/sw_ant/2206.html

The Sony AN-1 Active Antenna Coverage would be 150 kHz to 30 MHz
+ Longwave Frequencies = 150 to 500 kHz
+ Medium Wave {AM BCB} = 500 to 1700 kHz
+ Shortwave Bands {HF} = 1.8 to 30 MHz

IMHO - The Sony AN-12 Active Antenna would appear to be
a re-make {up-grade ?} of the Sony AN-1 Active Antenna.
