This is a "BRAND NEW" Power Antenna Cable for your Original Delco Factory Power Unit. This Cable is manufactured by us, ... The Antenna Source.  This cable is warranted for 1 year.  As long as your tube sections of your mast are not bent then this is the part that breaks the most, it gets brittle with age and simply breaks.

    We have two choices of cables, either the original plastic cable that came with your unit when new, OR, an Updated Very Flexible Steel Cable that will last well beyond the life of your vehicle, fix it once and done.
 

Note:  So if your Mast is not Bent and yet you hear your motor running and the mast will not move when you turn the radio on and off, all you need to replace is this CABLE.   This GM Delco power unit that you have in your car has a separate mast and cable system, allowing you to replace either your mast or your cable separately....
