Looking for a solution to solve your 114 115 116 123 or early 126 chassis power antenna problems? In my humble opinion the original power antennas on all 1985 and older Mercedes are justing getting too old to mess with anymore. I have tried myself to rebuild them only to have them fail again in another area. You can send them out for professional overhaul but that is expensive. Unless every electrical and mechanical part inside is replaced problems may return. New original exact replacements are no longer available.
I believe the Hirschmann universal automatic power antenna is a good alternative. Although not as robust or impressive as the original factory antenna, this unit will adapt easily to all models except the station wagon. It is inexpensive, attractive, reliable and relatively easy to install with these instructions. Due to its simpler design, the height fine adjust function is not incorporated. You will no longer be able to change the height of the antenna mastwhile driving. It will either be all the way up or all the way down. Most owners never use this function anyway and I feel it is a small “price to pay” for the money saved and the reliability regained. The antenna drive unit itself is a little lighter and smaller than the original
This will mount in all 114, 115, 116, 123, and 126 chassis sedans and coupes from 1968 to 1985. The complete step by step illustrated instructions written by Kent Bergsma will make installation painless. This five page guide will save you at least an hour of work over trying to figure out how to do it with the Hirschmann instructions.
