[. . . ] If I need a longer Sirius antenna cable, or a specialized Sirius antenna, where can I purchase one?I operate a business and wish to buy multiple Model Satellites with multiple Sirius subscriptions. Please contact Sirius regarding all commercial-related subscription queries. [. . . ] This fee is cheaper if activation is performed online instead of over the phone. Have a credit card available and be prepared to provide your Model Satellite's Sirius ID number and the name of the dealer of purchase. This number is located in the main menu and is also on a white sticker on the rear of the unit as well as on the side of the carton. Certain Sirius promotions require a commitment, but in general there is no commitment. However, signing-up for a year or more may make you eligible for certain discounts. If I am an existing Sirius subscriber, will my subscription fee be less for adding another subscription for the Model Satellite?Yes, but additional units can only be activated by calling Sirius, not via the Sirius web site.

The Model Satellite has a variable analog headphone output which doubles as a record output. It also has an auxiliary input for a CD player, MP3 player, or other device, a mixing input (to mix an auxiliary source, such as a computer, with the Sirius or AM/FM radio), a subwoofer output (for use with Tivoli Audio's Model Subwoofer), an external AM antenna output (AM antenna included), and an output for Tivoli Audio's Stereo Speaker. For more information regarding the operation of the Model Satellite, consult the owner's manual on our web site. Model Satellite FAQ's: Page 3 19. I noticed the Sirius reception signal level tends to change throughout the day. Due to the earth's orbit in conjunction with the satellites' orbit, the signal can fluctuate. The Model Satellite uses the same full-range speaker and sensitive analog AM/FM Henry Kloss tuner as our acclaimed Model One table radio. Without exception, we feel the sound quality far surpasses that of any satellite radio product on the market. Factor in the furniture-grade wood cabinet and it is also the best-looking satellite radio on the market.
