300D Antenna Repair

I know this is not exactly diesel specific, but it looks like the audio forum is more about radios and sound systems. So, the power antenna on my 84 300D was gunked up and not moving, so I took it out and cleaned it up with some steel wool and silicon lubricant, put a bit of grease on the mast and now it slides up and down smoothly. I put the mast back in the power unit and threaded the notched flexible nylon rope back into the gear and manually wound it down so I could install it back in the car. When I attached the plug, the antenna went into the full up position. The radio was not on and the car was not even on nor the key turned to accessories. The antenna switch has no effect in bringing it back down. Is it in some default mode? Can I reset it somehow to work with the switch?

There are two power wires. One is swiched on and off by the radio, and is used to raise the mast. The second is always powered, and is used to lower the mast. It sounds as if you've somehow swapped them.

I'll take a look. I believe the wire assembly that snaps onto the top of the antenna power box can only go on one way,but what you are saying makes sense. And it is raising rather than lowering the antenna, as the default when the power goes off.

If it is still the same you need to eject all the fibre gear and mast and refit it .Its not getting to its fully open possition to switch off You must replace the right way per instructions .You need a friend to turn on the redio as you feed the mast in to the holder.It will stop automaticaly as it goes down inside the unit .I can find instruuctions if you need them that came with my new replacment mast .Also keep oil and grease from the mast .as it moves up and down it takes dirt and grit with it. A light rub with silicon cloth.I use a gun cleaning cloth ,just for mine.

The step by step instructions would be helpful. I did wind the antenna cable all the way in before I put the box back together. Without it in the down position, I was not able to put the unit back in the trunk on the mounting bracket. Unless I were to wind it back in while the motor box is already mounted on the bracket. I imagine that would be very awkward.

I just watched a YouTube video of a guy replacing his antenna mast. It looks like what I need to do is mount the motor box but leave the mast out. Then feed the mast in, let it retract and screw it down after it has retracted. I may give it another go this weekend in the garage.

I gave it another go today but it still seems like the default is "up", whether I start in the up position or down position. Optimusprime, I will PM you and see if there is another way I can get the instructions from you.
