Antenna Motor A Must Technical Manual For An Electrician Is Changing A Broken Power Antenna A Do It Yourself Job?

Is changing a broken power antenna a do it yourself job? - antenna motor a must technical manual for an electrician

I have a 1990 Mercedes 300E with a broken antenna. It is a power antenna and they said that all (motor and antenna) (subject to change and not just the antenna) has to be. If I get the original equipment manufacturer (not as a substitute for market may or may not), a hobbyist (me) the job? What tools do I need? Thank you.
