NEEWER® Car Windshield Mount Electronic FM Radio Antenna
I keep thinking one day I will learn not to try something cheap hoping for a better outcome.<br /><br />This antenna does positively nothing.  I bought it hoping to not have to replace the old mast on the fender of my vintage car, no dice.  Powered or unpowered I got no more than when nothing was plugged in.<br /><br />$8 later for a standard fender mount antenna and all FM channels come in crystal clear.
