Neon II VHF Antenna Splitter

The Neon II VHF antenna splitter allows an AIS Class B and VHF marine radio to share a single antenna.

At its heart is SRT's Trident 2 splitter module which uses patented technology to ensure maximum performance from both the AIS and VHF radio. SRT’s advanced core technology does this whilst maintaining the radio transmission integrity and type approval compliance of both transmitting devices. SRT's Clear Call routing feature ensures VHF radio priority at all times, even in the event of vessel power failure.

The Neon II Splitter is ruggedised and certified IP67 waterproof and is the ideal accessory for Class B AIS installations, allowing easy and low cost installation where there are existing VHF antenna installations.
