antenna sticks , does not raise fully ....can anyone offer any advice on what lubricant to use

 

This is a topic that can go on for day! You can do a search and see why or you can use wd40. It displaces water, lubricates and cleans. Spray the antenna, operate it and then wipe it dry with a clean cloth from the base to the tip (to avoid pushing dirt into the layers) and then do it again. If your antenna does not operate properly after 2 tries look into repair or replacement.

 

if not simply dirtied up, either one of the sections is bent, or the little teeth on the riser-thingy is damaged. Replacement is pretty simple also.

 

Clean Antenna, a new band!

 

Most likely the plastic gear cord is damaged. Replacement is easy if it has not broken off inside the motor as mine was. I had to remove the motor and take it apart to retrieve the broken piece.
