>>
>> If the diamond pattern, bend the wire in a U right past where you

>> If a spiral, just move the insulated center wire to one side and twist

>>
>> In either case, at this point you should have a Y, with the legs of the

>> Wrap a rubber band around the handles of a small pair of long-nose

>>
>> Solder one clip to the shield on the free end of the pliers.
>>
>> Strip the center conductor and solder another clip to it.
>>
>> A small length of heat-shrink tubing can help stabilize the joints.
