replacement antenna

[ojingoh]

Hi guys I have a 1991 318i (4 door) and I'm trying to find out if the car's non- power antenna is original.  I was under the impression that all BMWs are power antennas.  What would be required to make it a power antenna?  mine has no mounting points in the body work, just the hole and the antenna lead.

Thanks very much!

Google or eBay search on BMW 318i Power Antenna Hirschmann - E30. You might also find one in a salvage yard.

My 91 318i had it from day 1, and I ordered mine without a factory radio.

I got some practice doing an antenna mast replacement on the same antenna in a 1990 325iC, so this is what I remember:

A triangular brass piece with two 8mm hex head screws attaches the antenna to the car frame along the wheel well, while the black ground wire is secured with a 10mm hex head bolt.
 
You would also hope they ran the electrical wiring and connector (C219 -- two wire (red and black) back there.
