Its a multiconductor cable with power, data and video. I have spliced a
lot
of these for sailboaters after the cable was cut for stepping a mast, etc.
Also put in a connector splice for one guy who had his scanner stolen a
couple time off his trailered boat. Frankly, I would go with a 5 meter
longer cable and post the short one you have on eBay. The splices are
difficult to weatherproof, the connectors will have to purchased from a
dealer or Raymarine and you will need some good soldering skills. I use
resistance tweezers soldering tools for these connectors. Some sailboats
that cut the cable below decks have used a standard terminal strip or
Euro-connector (set screw) in a weather proof box without problems. That
method might work OK for you. The best way to avoid losses and future
intermittents is go with a new longer factory made cable.

Doug,
I have a Furuno radar - old model 1720.

When I bought the boat, the cable had already been cut and an attempt had
been made to put in a terminal strip using crimp on spade connectors. I had
this working, but the signal conductor inside the small co-ax was so
fragile, it kept breaking off.
I also had some Euro-style terminal blocks, but I don't think they would
have been better.

I decide to try an Amphenol circular plastic multi connector plug and
receptacle - Quite a soldering and assembly job - there are a lot of
conductors! This seems to work, but once in a while I still get faults. The
assemble has proper sealing boots and I wrap it with self-amalg tape, so no
moisture gets in. Maybe I should use some dielectric grease?

I am thinking of relocating the radar to a stern post mount. If I did this,
I would have no joint, but I would have to somehow re-attach one of the
radar connectors - either the radome end or the display end depending on
which piece of cable I used. Can I re-use these? Any suggestions or advice
on this?




You have come across one of the minor flaws in the Furuno Radars.
That little center conductor has caused a lot of us Marine ET's
to feed our families, over the years. My solution was to strip
the insulation back 3/8" and then fold the wires back over the
isulatio., Then insert the insulation and wire into a larger
crimp lug, and carefully crimp both the wire and insulation in
the bigger lug. Then run just a touck of solder into the crimped
connection. Never had one come back with a broken video line
after that.
