Re: [Amel Yacht Owners] Range of AIS

Also, does this take into consideration the splitter is “powered” as opposed to a non-powered splitter? The specs of the powered unit claim negligible insertion loss. I can’t imagine they could claim this with a  50% loss.

Bob, That's interesting, I was told there would be a loss by the rep. for Garmin , approx. 2db, which was their argument for a dedicated antenna. I just did not and still don't understand why you have a loss assuming good connections and the antenna only servicing one unit at a time either vhf or ais.  Thanks, Pat

I'm new to this users group and joined to listen and learn all about the Amel's while my family and I search for a well-maintained used SM53 to buy and use in the Great Lakes.

Here's some theoretical numbers that I've calculated which may may be helpful in understanding what happens when using a 2-way splitter and a 3-way splitter:

2-way splitter...your theoretical insertion loss will be -3dB which is a 50% reduction.

3-way splitter...your theoretical insertion loss will be -4.77dB which is a 67% reduction.
