Raymarine's AIS700 is a Class B Automatic Identification System (AIS) transceiver designed for use with Raymarine multifunction navigation display systems
The AIS700 from Raymarine is a Class B Automatic Identification System (AIS) transceiver designed for use with Raymarine multifunction navigation display systems. As a Class B AIS transceiver, the AIS700 not only receives broadcasts from other vessels, it also transmits your own boat’s information too helping you to be seen on other vessels’ systems
• Full transmit and receive AIS for enhanced situational awareness and safety
• Latest SO-TDMA networking for longer range and faster performance
• Built-in antenna splitter simplifies installation with existing VHF radio antenna
• NMEA2000, NMEA0183, PC and SeaTalkng Compatible
• Software or hardware switchable Silent Mode for enhanced security when needed
Antenna Splitter Specifications
The AIS700 is a Class B AIS Transceiver with an Integrated Antenna Splitter. This means that a marine VHF radio can be connected to the AIS700 and, using the integrated antenna splitter technology, share a marine VHF antenna with the integrated AIS transceiver.
The marine VHF radio frequency band, which is used by both VHF radios and AIS transceivers spans the frequency range from 156MHz to 162MHz. VHF radios tend to operate at the bottom of the range, and AIS transceivers tend to operate at the top of the range. Some marine VHF antennas are optimized to provide the best performance at either the bottom of the range for use with VHF radios, and some are optimized for the top of the range for use with AIS transceivers. However, the AIS700 requires a wider band antenna to provide good performance for both the VHF radio and the AIS transceiver.
Using a VHF antenna optimized for VHF radio frequencies may cause transmissions from the AIS transceiver to be reflected back into the AIS700 due to the poor impedance match of the antenna and AIS transceiver frequencies. Although this will not damage the AIS700 (because AIS class B transmissions are of substantially lower power than VHF transmissions) it could result in the AIS700 triggering a system ‘VSWR’ alarm.
Raymarine DOES NOT recommend the use of VHF antennas optimized for AIS or Radio Frequencies as this can cause a VSWR fault alarm or permanently damage the AIS700.
The recommendation is to select a Marine broad band VHF Antenna that spans the VHF Radio Frequency range with the following specification:
