The Vesper Marine AIS / VHF / FM Antenna Splitter is used to share a single VHF
antenna for both VHF radio and an AIS receiver or transponder. It can also supply
a feed for your AM/FM radio.
Items needed to install:
•
12-24V DC power. Always install a 1A fuse and/or circuit breaker.
•
Four 3mm (#4) screws for mounting.
•
Two standard 50 Ω VHF patch cables (PL259) of adequate length to reach from your
selected installation location to your VHF radio and AIS receiver or transponder.
•
An optional BNC-to-Motorola Plug cable is available for connecting to most AM/FM
radios.
Installation:
•
Select a suitable location. Often this is near an existing VHF radio since the antenna
cable is located there.
•
The unit is water resistant to protect it against the marine environment, however it is
recommended to install it in a dry location.
•
If power will be switched with a circuit breaker, ensure the splitter always has power
whenever the AIS is active. This may be easily accomplished by using the same circuit
breaker as the AIS receiver or transponder.

Features:
•
Ultra low insertion loss.
•
Low noise amplifier improves AIS receive performance.
•
AIS sensitivity is increased to -119dBm when used with Vesper Marine transponder.
•
Fail-safe, always gives priority to VHF radio even if the power is switched off.
Indicators:
•
Green power indicator. The splitter must have power for the AIS to work.
•
Amber VHF TX is illuminated whenever the VHF radio is transmitting.
•
Amber AIS TX is illuminated briefly whenever the AIS transponder is transmitting.
•
Red “Check Ant” indicates an antenna problem such as a short or open circuit. This
indicator will light only when the VHF is transmitting on high power. You can check your
installation by switching to high power and pressing the talk button. Although this
indicates a potential antenna problem, it is only an indicator and does not affect the
splitter’s functions.
