Even plastic connectors can have shielding Larry. Besides, does you

AS with BALANCED NMEA-0183, you don't REALLY think they are ALL going to go
the distance and NOT ground data - to ground, do you?....(c;

There's no real Ethernet in the Ethernet router on the boat. The ports
aren't hooked to anything usable as an antenna. The Ethernet is all

Are they all going to shield the plastic instrument cases without being
forced to, too? Lots of them radiate through the cases.
