A015-TX Active VHF Splitter (for AIS transponders)
$273.72 ($228.10 excl. VAT)
The A015-TX Active AIS-VHF Antenna Splitter allows one VHF antenna to be shared between VHF and AIS devices:
- VHF radio (reception and transmission)
- AIS transponder (reception and transmission)
- AM/FM radio (reception)
- Built-in pre-amplifier providing AIS signal gain (typically 12dB) maximizes AIS reception and range
- VHF fail-safe functionality to continue transmitting VHF radio even if the power to the splitter fails
- Straight forward connection (no configuration required)
- Low power consumption.

Description
Description
This active AIS-VHF Antenna Splitter provides a typical AIS Gain of 12dB, while allowing one VHF antenna to be shared between,

- VHF radio
- AIS transponder and
- AM/FM radio
Specifically, the A015-TX allows the one VHF antenna to provide the following functions:
- Reception of VHF radio, AIS messages and AM/FM radio
- Transmission from VHF radio
- Transmission of AIS messaging from your AIS transponder
- Straight forward connection to the relevant devices
The A015-TX is an active splitter.
This is an important distinction, as, while many splitters cause signal loss, an active splitter actually provides a signal gain for AIS and minimizes VHF and FM/AM insert loss. The A015-TX’s built-in pre-amplifier amplifies the AIS signals, thereby increasing the AIS receiver range and reception.
Features
| Feature | Description |
|---|---|
| Power supply | 12V–24V powered |
| Power consumption | Low power consumption |
| Connector | Standard SO239 connector for VHF, AIS, and antenna connections |
| AIS gain | Typical 12 dB |
| Insertion loss | ≤ 3.0 dB for VHF radio, ≤ 0.5 dB for FM/AM radio |
| Preamplifier | Built-in pre-amplifier (typical Gain 12 dB) providing AIS signal gain and maximizing receiver range |
| Indicators | LED power and status indicator |
| Installation | Compact & easy to install |
| VHF failsafe | If splitter power is lost or fails, VHF radio remains functional with full priority |
Fully compatible with all AIS transponders and will maximize their performance.
Please note: The A015-TX is compatible with AIS transponders/transceivers. While it can also be used with AIS receivers, if you require an AIS ‘receive only’ splitter the A015-RX is sufficient..
