But how far can you get on the less than 9 watts you will have left after using
a cable
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.

From everything I've seen, tinned wire is recommended.

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

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

That's not a good idea. On a power boat yes, but a sailboat will usually
be listing when underway and with a high gain antenna flattening the
pattern you could be dumping the power into the sky or ocean.
If you go
Mil-spec RG-213 (not bogus RG 213 type cables) are well suited for this
application. The losses are not significant for what is, for practical
purposes, a line of sight application. The jacket is well suited for resistance
to ocean salts and UV. It's available at reasonable cost.

One fellow down the reply list sent you the Belden marine pamphlet, give
that man a prize.
The short answer is the biggest **flexible** cable you can manage. But
there are other considerations just as important;
1) Supporting the weight of cable. Clamp it at the top and bottom.
Don't expect
