LMR cable has polyethylene outer jacket and foam insulator so you have to be
very careful about sealing up the connectors. The LMR-DB cable is filled
with an inert gel to prevent water migration and is guaranteed for 10,
years. I used LMR-400DB with SMA connectors which are about the same
diameter as the cable and slip a piece of adhesive lined shrink tubing over
the joint.

If you are going to the masthead the ultimate in low loss would be
LMR-400 or 400UF. Slightly lighter weight than RG-8 with about half the

LMR type coax is real popular with the wifi folks but I don't know why
it has not been better accepted in marine VHF. It is lighter weight and
handles bends with less loss than the regularly used coax.


What glen said! LMR (Times Microwave) has the LMR series coaxial cable
in a range of sizes that will replace RG-58, RG-8, or any other commonly
used coax. And it outperforms all of the "old standards" by the specs
and in my experience.

Will check it out.

The recomendation from BoatUS was PVC jacket and tinned internal
conductor (ratehr than bare copper). And to avoid foam filled cables.

So?
PVC jacket, tinned stranded internal conductor, and..
What kind of insulation? Air?
