Automatische Antenne Hirschmann AUTA 6000 KE - Zerlegung und Analyse (Teardown)

Here I'm disassembling an old Hirschmann AUTA 6000 KE antenna I found at the edge of the forest. Despite the antenna's deplorable condition (sand and moisture in the housing, completely rusted DC motor, and shaky electronics), I wanted to know how such an antenna is constructed and whether it can be repaired. After various cleaning operations and analysis, I came to the conclusion that it is entirely possible. Components used on the circuit board (among others) Philips 225595-000 (unknown IC, datasheet not available) BUK 453 (MOSFET) D44VH 10 (PNP transistor)
