Default antenna trimming?

This discussion reminds me that my old Mercedes had a momentary contact
built into the power antenna switch that would let you adjust the
antenna length up and down from the dashboard. It was kind of cute but
never seemed to make much difference in reception. (Yet another
example of Germans inventing a problem so that they could solve it, I
think.) The radio itself was an old Blaupunkt and was a magnificent
piece of electronics, though. Vastly overengineered. Automatic
three-stage scan, direct frequency entry, and an alarm clock!


Germany of course had (has) no MW radio transmissions of their own - the
frequencies were removed from them after WW2. Which is why they had such a
lead in FM in the early days. So it might be their radio installations
were also better at receiving distant MW broadcasts.

But the other reason to stop the aerial going fully up was high speed
travel on the autobahn.
