The Antenna Coaxial Cable Power Supply Module
ANTENNA – this contains an efficient bicone element followed by a limiter, filter, low 3. Power Supply Module noise amplifier and fail safe relay. The limiter is a key feature of the antenna as it protects the internal amplifier from accidental high power radiation. The antenna’s ANTENNA – this contains element followed a limiter, 10mm filter, low noise amplifier housed an in aefficient robust bicone fiberglass radome with by a superior thick marine gradeand fail safe relay. The limiter is a key feature of the antenna as it protects the internal amplifier from accidental high aluminum mounting plate. power radiation. The antenna’s housed in a robust fiberglass radome with a superior 10mm thick marine grade aluminium mountingCOAXIAL plate. CABLE – One single assembly is used to connect the antenna and power supply. This cable is a good quality low loss coax, supplied as standard with N type COAXIAL CABLE – One single assembly is used to connect the antenna and power supply. This cable is a good male plug at each end. quality low loss coax, supplied as standard with N type male plug at each end. POWER SUPPLY MODULE – the power supply unit is 1RU housed a standard 1RU POWER SUPPLY MODULE – the power supply unit is housed in a standard rackinand will accept any input rack and will accept any input voltage form 85 to 264VAC and a frequency of IEC voltage form 85 to 264VAC and a frequency of between 47 to 440 Hz. Connected using an international between 47 to 440 Hz. Connected using an international IEC standard power lead. standard power lead. This module outputs the received RF signal to an external ship system via a standard N type connection. This module outputs the received RF signal to an external ship system via a standard N type connection. OPERATION – the operation of this antenna is quite simple. Once connected & power is applied, the receive signal is limited, filtered and amplified the antenna & fedantenna down the cable to Once the power supply & module. OPERATION – thebyoperation of this is coaxial quite simple. connected When power is switched off to the antenna the filter & LNA are by-passed by internal relays which then connects power is applied, the receive signal is limited, filtered and amplified by the antenna & just the passive antenna & limiter into thecable circuit. fed down the coaxial to the power supply module. When power is switched off to the antenna the filter & LNA are by-passed by internal relays which then connects just the passive antenna & limiter into circuit. 1

Power Connection:
International Standard IEC Power Plug required
RF Connection:
N type standard Male Plugs will connect to this panel (Note Antenna connection assembly is supplied in the kit)
Operation:
When the power is switched off to the antenna, the filter & LNA are by-passed by the internal relays which then connects the passive antenna and limiter into circuit for radiation protection.
