Brent, Great briefing, many thanks. Likewise for the subsequent posts.
It's well timed as I'm about to fit AIS and also researching kit to install for 4g/LTE comm's whilst cruising in the Mediterranean. I'd identified the need to use lowest loss possible coax cable, is the TMS LMR-400 cable you refer to a trade name or is that an industry standard specification? Please excuse the ignorance if this is a dumb question.
