• | A non-stretchable rope (such as Spectra® or Kevlar®) with the same length as the fourth-wire cable. |
• | Duct tape |
• | Eight-inch strain relief |
1 | Attach the rope to the fourth wire cable using duct tape approximately every one meter. |
2 | Make sure that the total length of the rope is shorter than the length of the fourth wire cable. This will allow the rope to take up the tension.
|
3 | Roll up the fourth-wire cable onto a separate drum. Important
Make sure that the block is sufficiently dimensioned to allow the fourth wire to run undisturbed through it during deployment
and retrieval. The block diameter should be at least thirty times the cable diameter.
|
4 | Tie the other end of the rope to the eight-inch strain relief. |
