Opinions on whether I'm buying the right connector

My shiny new B&G 4G radar arrived last week. Now that I have the unit, I've started planning the installation.

Most of it is straight-forward, the only minor glitch is that the main cable that has to run from the MFD to the radome is one long section of 12-conductors. I want to put a disconnect of some sort at the base of the mast to make it easy to unstep the mast.

I contacted B&G on April 13 to ask if they had a connector specifically for this purpose that I could buy. They have not deigned me worthy of a response.

So I did some hunting and found this:

It'll require some soldering, but I think I can remember how to do that. Does anyone see any issues with using this connector that I'm somehow missing or have a better recommendation?

I would think you run wires from bottom of mast to terminal blocks that are mounted on bulkhead above the sole....out of water/weather.

That's certainly another option. I was leaning toward this type of fitting since it make it impossible to hook things up wrong, whereas human error could lead to a mistake reconnecting to a terminal block. I suspect that accidentally putting 12v DC through an ethernet wire is a bad thing.

Are you stuck on a mast mount? Generally with a stern post you can run the cable direct. I think the loss in range is not a real big issue at sailboat speeds. Plus mast-mounted radomes can be hard on headsails if you do a lot of upwind work

They should be color coded.
That connector is a junction...as is terminal block...just different design for different use.
You may have several junctions along that routing....end to end.

Very roughly....
he will approx double range on-mast....again roughly...from 3 miles to 6 miles...to water level.
Easy math for this online...got no trig in my bucket...

Then add the targets...land seabound etc...and the gain is much greater.

i think i have an understanding of the arguments for both views.

Isnít that just a NMEA2000 cable? You can purchase them in many lengths.

No. It is a specialty cable. It _appears_ to have a UTP ethernet cable alongside 2 power leads (I'm guessing one power lead is for standby and the other for full power) The cable in question runs between the radome and some sort of "interface module". The module has standard connections to N2K and 12v power and ethernet so there's some sort of translation done.

There's 12 wires. With that many wires, it's easy to get into the "is it white with a green stripe or green with a white stripe?" situations. Just at a glance, there a 2 solid black wires, for example.

Thanks, Bill. Thatís good to know. Iím planning to get one for my power boat and had contemplated only a NMEA2000 between the radar and MFD.
