If you have a Hirschmann AUTA 6000 KE antenna that does nothing when on (no sound from motor), then this module is probably the culprit, as these burn out.  Tested and works.  (Roughly half the ones I test are dead).  This definitely works.

If your antenna motor makes a noise, then this unit is NOT THE PROBLEM.  You only need to replace these if your antenna does nothing and makes no noise.

Due to buyer fraud, I have to have tamper proof stickers on these units.  If you open the case (thereby lifting the stickers) you will not be able to return this.  There's no reason to open the case.  This simply pops onto your existing antenna.  As I mentioned, this one works, as I fully tested it on an actual AUTA 6000 KE antenna.  20 years on eBay, a seller you can trust.
