The antenna is supposed to click when it is all the way up or down, its just the clutch. Measure the antenna, if it extends at least 31 inches, it doesn't need to go any farther for optimal reception. You can take the mast with it's nynlon whip out of the assembly and work it by hand. Once you have it fully extended, buff the crap out of it wit chrome polish and it should then slide smoothly.
