Splicing Antenna Wire
This is a variety of antenna wire splices. All of them are stronger than
The primary problem with steel core wires is water ingress. Water causes the
Many wires, in particular fine wires like in stranded copper-steel wires like
This is also true for steel electric fence wire, which usually has a very
Copper Sleeve Splice
This is the most attractive splice, and pulls through most insulators. I cut
I crimp the copper near the center to hold the wire in place, and heat the
This is a splice after pulling the wire past wire breaking strength.
The advantage of this splice is total sealing of steel ends from moisture.
The disadvantage is obtaining properly sized copper tubing, and having to saw
Heavy butt splices are strong enough, if the wires are overlaid through the
Modified Western Union Splice
For rapid heatless splicing, a modified Western Union splice works well. It
I clean wires with a rag and automotive scratch removing compound, or burnish
Sharply bend the wires by hand at the starting point of wrap.
Wrap the wires tightly by hand, using the long ends as a lever.
Keep the wire turns butted tightly against each other.
This is a finished wire splice WU or lineman’s wrap.
Although it looks ugly, I added an additional step. This step is critical for
This single step will be the difference between a splice failure under severe
If the wires scratch out here, it takes a long time for rust to work through
This is the splice above, after the wire was tested by pulling until the wire
Pliers marks are visible on the twisted end. That is a point that would
