Antenna X Power Antenna Watch out! : eBay Guides

Antenna X sells cheap imitation stuff, which may be fine if you have a normal car.  In my case I knew an RX7 had special wiring and corresponded prior to buying and was assured the antenna would work.  It literally melted when installed, and the guarantee... well I think they disappeared off the planet the next day.   and since they shipped 28 days after the order, the paypal guarnantee was also void.  Pretty smart.  So if you are sure you have a positive action power antenna - one that goes up or down when you apply power, then this stuff is cheap but should be fine.  If you have any special requirements as Mazda and I assume Mercedes, Jag,  and any unique Marque would have, stay away even if they guarantee you that it will work.  The $11 isn't worth the damage you can do to the car or your blood pressure.
