I have been using this product to connect my VHF, AMFM Radio, and an AIS receiver all from the same VHF Antenna, and works just fine without any noises.
Great radio reception, NDR1 is now well received in the entire Danish South Sea. That was not possible before. The sea radio reception shows no recognizable deficits. Clear product recommendation.
In principle the device kinda works so I do not have ground to return it. However, the device has huge(!) impact on antenna's functionality. Without using this splitter I can receive AIS targets 20NM away. When using this device, I receive AIS targets only 5NM away - at the same time
Huge disappointment, bad value for money, will not continue using.
