Dumb Antenna Question

[Maroon 300D]

Umm....the antenna on my '85 300D is supposed to have three sections, right?? It was only working properly for a couple of days after I bought it, and I can't quite remember what it looked like. I have WD-40'd it and was able to get one section unstuck, so there are now two that extend, but the middle one (if indeed there is one) is proving to be a bear and lubing and pulling (no dirty comments, plz) isn't working.
