Description
Bottom Line Up Front (BLUF): The MRC MAD-100 Communal Aerial System (CAS) receives, amplifies, and distributes terrestrial TV and radio signals to up to 96 subscriber cabins (expandable via MAD-100A sub-amplifiers). Paired with the AT-100 omnidirectional active marine antenna, the system features built-in Automatic Gain Control (AGC) across MF/HF/SW, FM, VHF, and UHF broadcast frequencies.
1. System Overview & Marine Engineering Architecture
Manufactured in South Korea by Marine Radio Co., Ltd. (MRC Korea), the MRC MAD-100 Communal Aerial System (CAS) with AT-100 Omni-Directional Antenna represents state-of-the-art maritime equipment designed to fulfill stringent international safety conventions and classification requirements. Tested against severe marine vibrational dynamics, thermal cycling, and continuous electromagnetic interference (EMI), this equipment delivers mission-critical dependability for deep-sea merchant vessels, offshore rigs, workboats, and naval patrol vessels.
Featuring industrial-grade internal components, galvanically isolated power conversion stages, and robust ingress protection, the MAD-100 prevents catastrophic single-point failures. Navigating officers and marine superintendents benefit from streamlined human-machine ergonomics, intuitive operational workflows, and verified compliance during annual safety and radio surveys.
