I ordered the antenna for Opel Zafira A. Mechanical installation was smooth, electrically musss you solder the cable, since the adapter plug does not fit the original Opel plug. This is relatively easy with a little experience. But the Emfang the antenna is very bad. Only extremely powerful transmitters can be handy tips. My favorite radio station, I could easily received so far with the original antenna is receivable only with noise and constant interruptions. I will expand the antenna again and yet to buy a (expensive) original antenna. Unfortunately, I can no longer return the antenna because I have cut off the plug.
