The Standard Version MEDIAN BUCs offer higher gain to reduce the need for line amplifiers in long cable runs (IFL). In contrast, the WGS-Compatible Versions have lower gain to allow operation with IF signals driven up to 0 dBm.

Cyber-Hardened Intelligent BUCs are designed to enhance satellite ground terminal security for industries requiring optimized and flexible protection. These BUCs implement effective security management controls—including encrypted authentication, privacy, and access control—to ensure end-to-end message transmission. They help protect against session hijacking, password attacks, and eavesdropping.
