re-connecting a cut radar cable

[sarabande]

I have the opportunity of a reasonable small Radar set. The cable 'twixt the display and the scanner has been neatly cut because it was behind a new headlining.

Are there any techy issues of which I should be aware in joining the colour-coded cables together, or is it just a question of doing a 'proper' job, please ?

TIA

Both my Benes were cut, they have/had choc box connectors in a generic splash proof box tucked inthe head lining by the mast, no probs ever

Installed last year and re-installed this month my Furuno radar. Cable cut and re-joined with chocolate block connectors. About 25 wires I seem to recall.
Normal and no problem.

My old Radar was installed with Choc Bloks. However, I have read on here that performance is compromised. What impact the compromise may have on a radar, I have no idea but there is a reason for all that shielding in the cable.

The first 5 threads from this search of YBW cover the issues (negligible) and also give some connector types. It also suggests how to deal with any coaxial using connectors and metal boxes.

I had Lowrance broadband radar fitted a couple of seasons ago. Over this winter, I've had the standing rigging replaced. I had to cut the radar cable with a hacksaw in preparation for the mast being stepped. A gut wrenching experience. The cable was 12 core, shielded. I visited my local Maplins but could not find anything better than choc block connectors. I also bought an aluminium case to house the joint and re-establish the screen. I carefully rejoined the cable laying it in 3 blocks, each of 4 connections. Wrapped the whole thing in bubble wrap and stuffed it into the cavity. Works just fine, pleased to say.

The one tip I was given is that it is better to twist the two wires together and put them into the same side of the chocolate box. Mine is done in this way and I have had no problems.

Tidiest and most professional way is Deutch connector(s) (up to 12 per plug / socket) contained in an ali project case with compression glands to maintain shield integrity. Or as has been said, a choc block bodge, but at least put bootlace ferrules on the stranded conductors before screwing down on them which can damage the stranding and compromise performance otherwise.

The 19 pin should be enough but make sure you check the number of cable links first. The beauty of this is when you need to unstep the mast you just unplug the whole thing. There are also protective covers for both sides of the connection which also work superbly. Possibly not the cheapest m on the market but very well made. No connection (pardon the pun!) etc just a very happy customer.

As an ex RF engineer I was concerned about the connection of our radar cable using a chocolate block in a case hidden behind the headlining. As we can often see returns from ships (I assume must be their superstructures) at over fifteen miles away I can't believe that the performance has been degraded too badly. The scanner is quite high up...
