Used this splitter for a Digital Yacht AIS. Works flawlessly for AIS signal input and output, radio priority works for inland and marine radio, plus great radio reception.
Depending on the technical requirements, I can recommend this device. The telephone support is excellent, and if anything is unclear, he is very competent to help.
I didn't connect the radio, AIS and radio worked well. The cable lengths of the supplied radio cables were good for me. As end devices I have Simrad AIS and radio devices. The plug on the radio was not suitable. I have a Blaupunkt car radio in the console. I continue to use the old active antenna.
Works perfectly and avoided to install a new VHF antenna for AIS with all the mess that would be to pass all cables. It improved a lot the reception of FM radio too -)
I purchased this product and would have preferred to have been told before that it did not work with EM-trak B100 transponder. It receives the targets but it does not transmit my position and triggers the red led on my transponder. Installation check 10 times. I am very disappointed.
