Vesper SP160 Installation Manual

SP160 AIS / VHF / FM Splitter - Installation Guide
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.
