The Chaparral 100C Plus, equipped with the VideoCipher II Plus module, is a professional-grade satellite television receiver from the late 1980s and early 1990s, designed primarily for the reception of encrypted C-band satellite programming. It was a key component in the early days of direct-to-home and commercial satellite TV distribution, functioning as both a tuner to select satellite channels and a descrambler to decrypt signals protected by the VideoCipher II Plus encryption system. This system was widely used by premium cable networks and early satellite providers to control access to their content, requiring an authorized decoder like the 100C Plus for viewing.

The receiver featured a robust tuner capable of scanning the full C-band spectrum (3.7 to 4.2 GHz) via a large satellite dish. Its integrated VideoCipher II Plus module handled the decryption of analog video and audio signals after receiving authorization data transmitted via the satellite feed or via a separate phone line connection for pay-per-view events. The unit included standard video outputs (such as baseband composite and RF) to connect to a television or distribution system. Control was managed through a front-panel interface or, in many cases, a separate remote control for channel selection and accessing system menus.

As a product of its era, the Chaparral 100C Plus represented high-end consumer and commercial satellite technology before the widespread adoption of digital DBS (Direct Broadcast Satellite) services like DirecTV and Dish Network. It is now largely obsolete for practical television reception due to the transition to all-digital transmission and modern encryption standards, but it remains a notable piece of broadcast and satellite technology history.
