For sale is a military cable for radars W-2. It is a multiconductor cable, looks like (looking at pins) that some conductors are a little bigger than others. This is a super expensive cable that cost our armed forces many thousands of dollars (listed as 16,000 dollars). Very durable and flexible.
I purposely got a DeWALT drill and my arm into the picture so that you can guess the size of the cable. On the picture where I bend the cable, you can see how flexible it is.
