Interesting question. Raymarine had at one time strictly recommended
against breaking their radar cable and adding an in-line connector anyway,
anytime. I did it with a cheap ten pin connector on an SL-72, and had no
problem for several years. I then took that radar from one boat to another
boat, and after reading the FAQ's on their web site, which grudgingly
admitted that a terminal board or connector was possible, substituted a
terminal board for the old connector. I was unable to get the radar to work
until I replaced the terminal board with another connector. I sense that
these connections are indeed sensitive. I'm not sure which lines are
sensitive, but suspect that it's the coax leads.

Which brings up an interesting question. Is it permissable to install a
plug and receptical at the mast partners so that you don't have to
unwire everything back to the display when you pull the mast?

Ideally you should run the cable inside the mast and again, ideally
you
should install it while the mast is out of the boat. This would allow
you to
get secure it and keep it clear of the internal halyards. (seperate
topic).

The biggest problem is the connectors on the end of the cable. In my
experience, (three Furunos) the antenna end connector are the smallest
and
if these connector shells are still to big to pass through access
holes/wireways, then the shells can be removed. (for the Furuno, no
special
tools are requird (seperate topic, again). Once the shell is removed the
contacts on the ends of the wires should be protected, especially the
small
coax cable.

The above being stated, you would of course, start from the radar
display
location and work you way to the mast and then just follow the route of
the
mast electrical wiring. I always feel that a mast junction box for the
radar cable should be part of the standard installation but I have never
seen one yet. I guess if you were going to pull the mast in the future,
you
could disconnect at the radar scanner and pull in a chase line while
pulling
the radar cable out.

The connector shells at the radar would have to be done while aloft but,
again, I found no need for special tools. Just a list of which wire goes
in
which connector shell and in what location. My Furuno manual provided
all
that detail.

(All the above was learned the hard way and only after I had damaged
that
little coax signal wire. Your welcome to benefit from my experience.)
