KVHF-4010-50: 50W VHF Transceiver for GMDSS Coast Station
The KVHF-4010-50 transceiver works in the maritime VHF frequency range from 156MHz to 162MHz and can deliver up to 50W of RF signal into a 50Ω load in transmission mode.
The KVHF-4010-50 transceiver uses up-to-date technologies and has native IP capabilities with the following features:
- Control through a high level WEB server (both for settings and monitoring),
High level Monitoring through SNMP (MIB supplied) as an option,
Data input both for voice and DSC fully compliant with the ED137-B standard (VoIP with SIP),
LCD for local settings & monitoring as an option,
Voice accessories for local use (microphones etc.),
The KVHF-4010-50 transceiver is specially designed to be installed into a maritime coast station fulfilling the GMDSS requirements. It fulfill the requirements according to EN 301 929-1 ETSI Standard for stationary sea radio units and guarantee a reliable operation, even in long time stress operation.
The KVHF-4010-50 transceiver is fully integrated inside a 19" - 3U rack with single phase 100/240VAC - 50/60Hz for an easy installation on site.
The KVHF-4010-50 transceiver can be used both for voice (or Phony) and DSC applications (DSC encoder / decoders included, VoIP encoders / decoders included).
Thanks to its experience in maritime communication systems, KENTA can propose turn-key VHF coast stations integrated into a 19'' rack (with antennas, coaxial cables and connectors, duplexers, filters, UPS etc.). Click here for more information.
Power also available : 25W
KTX-2012-1000: 1kW PEP MF/HF Transmitter for GMDSS Coast Station
The KTX-2012-1000 transmitter works in the MF/HF frequency range from 1.6 to 30MHz and can deliver up to 1 kilowatt PEP of RF signal into a 50Ω load. The KTX-2012-1000 transmitter uses up-to-date technologies and is from now ready for the incoming NAVDAT HF system:
- The RF signal is generated by a digital synthesizer with DSP and DDS,
- Use of last generation of MOS-FET solid-state power amplifiers,
- An IP access for monitoring and remote control is present in addition to the common RS232/485 access,
- A digital audio over IP access is present in addition to the traditional analog access (VoIP with SIP / ED137B),
Web based application software for remote control & monitoring. SNMP Agent in option (TRAP supported)
The KTX-2012-1000 is specially designed to be installed into the maritime coast station fulfilling the GMDSS requirements. It includes one 19" - 24U cabinet (without option), the power supply, the synthesizer, the amplifier and the harmonic filter for an easy installation on site. The main power supply is single phase from 100/240VAC - 50/60Hz.
The KTX-2012-1000 transmitter can be used for voice, DSC, NAVTEX ( 4 209.5kHz) or other purpose (USB, Digital Modulation etc.).
As an option, the KTX-2012-1000 transmitter can control the external KTU-2052-1000 Antenna Tuning Unit (ATU), if the transmitting antenna is not a wide band one.
Other available options are:
- LCD Display for Local Control
- Integrated Matching Box
- Redundancy Switch 2:1
- Tx Antenna Matrix ('M' inputs -> 'N' outputs)
- SNMP Agent
- Local Voice Operator Console with Integrated MF/HF Voice Receiver
Power also available : 2kW and 5kW.
KTU-2052-1000: 1kW MF/HF ATU for GMDSS Coast Station
The KTU-2052-1000 Automatic Antenna Tuning Unit (ATU) is a professional coupler, which can operate on a whip or a wire antenna configuration in the RF band 1.65MHz to 30MHz to a 50Ω transmitter (the KTX-2012-1000 for instance).
The KTU-2052-1000 is integrated inside an IP65 large plastic resistant to temperature.
The KTU-2052-1000 is connected to the transmitter through a coaxial cable, a power cable and a shielded control cable.
Maximum RF power input is 1000W PEP.
The coupler network configuration is a PI or L type; sensors continually monitor the state of the tuning and relay this information to the processor.
Power also available : 2kW and 5kW.
KENTA can also provide the antenna on-demand.
