Yes. An antenna splitter allows you to use your current VHF antenna instead of fitting another one which will generally lend itself to an easier installation. There are trade off's between using a splitter and having a dedicated antenna for your AIS system, read more about that in the previous FAQ.
If you decide to use a splitter, be sure to get one designed for use with your AIS system. A receive only splitter differs in functionality from a splitter that also allows you to transmit on the AIS path. Damage to either your VHF or your AIS equipment may occur if you use a splitter not well suited to your AIS system. If you have a transponder you must use a splitter designed specifically for use with AIS transponders, like our SP160 Antenna Splitter. Our splitter can also be used with AIS receivers such as the AISWatchMate 750 Receiver.
