That is a lot of user power in a single unit. As it notes, it does require separate antennas, or maybe run both of those coax to a splitter to single antenna. Might depend on the Standard Horizon installation specs.
I highly recommend an AIS receiver at least. The pluses far out way the negatives. The fears of MFD clutter are really unfounded, and the benefits of nearly instantaneous CPA and TCPA (Closest Point of Approach and Time to Closest Point of Approach) are way good.
Yes, there are always AIS units left on in harbors and at anchor. Some of them are being used as anchor alarms, others are monitoring working voltages, and some are just ..... on. Yup, they are a pain, so turn down the alarm volume. A small bother for the added safety of the AIS, that sees around corners and over islands. Something your radar cannot do.
Many of the pluses for the SH 6500 are found on the ICOM 605 which could be a good option if you are looking to upgrade without adding the B class AIS transceiver.
