After some years , the Hirschman antenna in SWMBO's '82 240D began squeaking , she nagged me to lubricate it and I didn't so it naturally seized up in the lowered position leaving me sans radio .
I used the 13 MM toolkit wrench to loosen the nut then turned the radio on and it puked up the stuck antenna , I was unable to get two of the sections to extend by hand so I hooked the tip in a file cabinet @ work and yanked really hard albeit carefully as it's easy to bend these things and once bent it's game over .
Then I use Nev-R-Dull <magic> wadding to polish the rusty and dirty chrome shafts , it still didn't extend and collapse easily by hand so I collapsed it and got my lint free clean rags out and used starting fluid (ether) to wash the nylon cable and i dribbled some of that inside the collapsed shaft whilst holding the antenna up side down , let it soak a moment then began extending and collapsing it by hand , cleaning the spooge off as it came out .
I also sprayed the ether up into it from below , in time the clean white rags stopped showing any dirt / crud / spooge so I hand dried it all , allowed to dry then lubricated it with some oil I had at hand .
I'd wanted to use silicone spray or grease as Hirschman and M-B both suggest silicone lubricant but I didn't have any handy .
In any case it works like new again and the radio plays fine , even on AM .
