I have been in a big discussion with the guys on my boat list about the
right coax for running up the mast for VHF marine radio.
Keeping in mind that we are talking about a 70' or so run going up the
center of an aluminum mast, in a salt water environment, and the radio is
limited to 25 watts.
Not having been in the situation to have to rely on the radio while
out enjoying the water, I would still use the best I could get.
I dont know the turn radius of LMR 400 or even 600 but I would
seriously consider something along these lines and avoid all 8x cable.
Being locked in to the power
My experience with LMR 400 is that even with the factory connectors it leaks
water like crazy. Wouldn't want to have that happen in the salt air.

I would Suggest looking at either aandrew FSJx-50 or LMR 3/8 or 1/2 heliax
type cable (100% solid shield) and if available a direct burial or underground
type jacket for additional water infiltration protection. Go the the home

The only issue I would have with Heliax is the possiblity of cracked and broken
solid conductors due to vibration and repeated flexing. If I were the vessel
owner, I'd use a good grade (Belden or equivalent) of RG-8 (X if you want).
There are not a lot of terrain features out there. I'd think
Looking at the list below, you can see that the 1/4 and 1/2 Superflex Heliax
have a very modest loss at VHF frequencies. I would use the 1/4 superflex.
It is very accomodating to bends, although I know of no coax that is
completly salt water-salt air resistant. I think that part of your

You certainly don't want just any old coax. You for sure don't want any type
of hard line run up the mast as the flexing will break the center
conductor or outer conductor.
You want to have a stranded cable such as RG8 type. Also don't use any type
of foam dielectric type cable on a boat as the

Mil-spec RG-213 (not bogus RG 213 type cables) are well suited for this
