Inter-communication Entertainment System for TV and Radio Broadcasting (CAC-953)

Communal Aerial System (CAS)

CAC-953 system is a maritime antenna system specially designed for vessels, and includes a broadbrand amplifier that can amplifies and distributes signals from all band radio broadcasting in MF/HF/SW and FM, TV broadcasting in VHF/UHF, and VTR/DVD signal interface.

It uses an Omni-directional antenna that can receive stable propagation signal during sailing for TV, and uses the whip antenna to receive the radio signal. It has a built in broadband amplifier with AGC (Automatic Gain Control) to prevent the degradation of output when signal is weak.

In addition, it is maintenance free after installation due to the robust design. After installation, once power is ‘ON’, all functions are fully operational automatically.

The comunal Aerial System is tested according to IEC60945 and certified for CE by DNV.
