mine is stuck @ a certain point. how do i go about greasing it up?

To grease the antenna you need to take it out and open it up. If it just needs grease then this is worth it to just take off the inside panel and take out the antenna. Then just open up the case and add some grease.

Otherwise just get a new one. They tend to go out all the time. I just turned mine to a manual one and saved my self some $$$

where do you get grease? and is it called grease?

how do you do that? i cant just apply some grease to it when its up?

It is a white grease that is probably teflon grease. You could probably add it to the shaft of the antenna when it is up, but it might not work as well if you had taken it all a part. I guess it would work.

Is oil, WD40, a no-no?

If you use WD-40 it might work, but it might later have the same problem since it evaporates. You might just want to give it a try.
