I have three vessels operating in Bering Sea using the Marine settup. The weak link is the connection point to antenna. Several of the shore side ones in Aleutian islands some friends had all failed here. You can fit the RV unit in a 24" dome the marine ones need a 30". Not cheap. We built custom enclosures and have PTFE covers. I believe the KVH domes are ABS.we see it’s a RV non tracking. We are in Hawaii now taking delivery for the Alaska season. Scrounge an old dome when I get there to hide Elon thing in. Anyone got any good ideas I have been told it has to be enclosed. I am electronics dunce but gifted tig welder so the mounts might be ok lol
I would guess you could pot cable point effectively, the cable and antenna are robust and probably not something I would worry about other than extended multi year stuff common to anything on a boat in the sun.
