Keep the
ends dry and they'll last a long time.
UV affects them, too (not only the 'brittleness' of the sheath, but the
plasticizers and solvents that work their way into the core, changing the
characteristic impedance). Once IN the mast, that's not a problem (only
moisture, then), but how was it stored/kept prior? If it's not virgin
cable from a reputable source, you just don't know.
I guess it depends upon whether this is a project to make the boat
"sellable", or if it's an attempt to maximize propagation.

Not selling them...just setting them up to Use them
Im not terribly concerned about ultra long range propagation...Im only
lake and bay sailing
Do they make whips for console radios? You don't really need the
height for local chat. 1' and 3' whips run from $15 on up.
Will these work?
This one is an AM/FM music type radio antenna

Something to keep in mind...is deck space.
My little Windrose 18 is only 18 feet long. The deck has the mast, all
the shrouds, the rudder, the outboard motor, the jib/genoa sail
sweeping the forward 1/3-1/2 of the deck, the movable hatchway,
any/all ropes and lines that come to the cockpit..and the cockpit
itself.
There are wide open spaces on top of the deck......until there isnt
as the sail sweeps that portion of the deck while changing
directionis. It can get pretty busy up there so far as space to put
Stuff attached to the boat. Add a bbq to the stern of the boat..

(one of my clients btw)
fishing rod holders, grandchildren to hold said rods, sodas, an
outboard motor and its controls (and fuel tank), fenders, other lines
(to hold the fenders and to tie to the dock) etc etc, rails and safety
lines (grand kids remember) and places one can put Stuff have to be
plotted out pretty carefuly.
This doesnt include futzing with boat trim either...weight forward/to
the stern/port/starboard etc etc
That also means an anchor (generally on the bow pulpit and the rope
its attached to...lol) and so forth. Add a couple kids or
adults..and it can get really cozy for space to mount stuff
So putting the antenna on top of the mast (with the wind direction
indicator, any wind Speed sensors etc etc) can help clear up
some..some space down on deck

If sailboats were like bass boats...laugh..it would be easy to stick
Stuff anywhere you want it.
Half the fun of rigging a sailboat is doing it effiently so one can go
sailing without ripping the bbq out of the deck and tossing it into
the water..or ripping one of the grand kids OFF the deck and pitching
it into the water (Grin)
Then there is cabin layout..inside...another interesting
challenge...lol
Ice chests, stove, sleeping layouts, spare sails, fishing rods, nets,
portapotti, sleeping bags, clothing, electrical gear (AM/FM/MP3 stereo
system, VHF radio, CB radio, batteries, chargers, solar panels,
diapers (blech!) etc etc.
Think of it as putting a machine shop in a small garage or cargo
container..where you cant drill holes in the walls..least not
easily...LOL
Im rigging the Windrose 18 to be a "single handed sailer" which means
everything comes back to the cockpit so I dont have to crawl all over
the top of the boat to raise/lower (3) sails, adjust sail trim, raise
and lower the centerboard, steer, grab a Dew from the cooler, chat on
the radio(s), change to a new music source etc etc etc.
Thats half the fun of doing a restoration/upgrade......the boats came
out of the factory back in the 60s/70s/80s rigged as simple and as
cheaply as possible to meet buyers ability to pay and a lot of Stuff
then, was not considered a necessity as it is today (cooler, music
radio, batteries to run all the electronics..a charger and solar panel
to keep them charged...etc etc Hell..finding a place for a laptop
was never an issue way back then..it can be today with all the
computer navigation systems in everybodys hands (which I wont be
needing..until I go to the ocean for a week)
