Need to replace the power antenna mast since the plastic ribbon inside has broken. Need best place to obtain reasonable replacement. Thanks.

 

I did my antenna a few years ago, got the antenna mast from EBay. There is one available available for $20. Had to pull my antenna assy out of the car and re-grease and clean the insides. There was dried grease and gunk from years of use. It has been working well for a few years now. I just need to wipe the mast every now and then and use a light lube like WD40 on the mast. I should use something else that does not collect dirt as easy but in an emergency it worked to stop the struggling.
