Introduction

The QK-A015-RX splitter allows one VHF antenna to be shared between,

VHF radio
AIS receiver and
AM/FM radio

The A015-RX allows the one VHF antenna to provide the following functions:

Reception of VHF radio, AIS messages, and AM/FM radio.
Transmission from VHF radio.
Straight forward connection to all relevant devices, with no configuration required.
VHF radio always has priority and can always transmit in the case that the power to the splitter fails
Low power consumption.

The A015-RX is an active splitter. This is important, as, unlike many splitters that cause signal loss, the active splitters actually provide a signal gain. The A015-RX’s built-in pre-amplifier amplifies the AIS, VHF, and AM/FM signals, thereby increasing the receivers’ range.

Please note: The A015-RX is compatible with AIS receivers only, it is not designed for AIS transponders/transceivers. For AIS transponders/Transceivers you would require the A015-TX

Connections

The A015-RX has five connections:

Power cable: connect to 12V-24V DC power
VHF Antenna: SO239 connector for VHF antenna
VHF radio: SO239 connector for VHF radio
AIS: BNC connector for the output of the AIS signal
FM/AM: BNC connector for the output of the FM/AM radio signal

Installation

The A015-RX is a plug-and-play device. No Configuration Required.

IMPORTANT: Connect the VHF antenna BEFORE connecting any other devices!
Connecting powered devices to a Splitter before connecting the VHF antenna will damage your devices.

Remove power source from all devices to be connected.
Connect the VHF antenna to the Splitter before adding any devices.
After the VHF antenna is connected, connect the VHF radio, AIS receiver, and FM/AM radio to the A015-RX Splitter.
Re-power all devices.
Test use checking status LEDs light up when expected.

Status LEDs

The A015-RX has three LEDs that indicate power and working status.

The VHF fail-safe means that the VHF radio has full priority and will remain functional, even in the unlikely case that the Splitter would fail or lose power.
