Apologies if I am misunderstanding the resurrection and recent posts on this, but another option is to add a dash switch that can disable the automatic down/up operation of the antenna. I did that to mine when I bought it about 14 years ago, and on the rare times that I want my antenna to go down and stay there, it still works just fine on my '99, because it never wore out. I can make it stay up, make it stay down, or let it revert to the automatic up/down operation.
I looked in my bookmarks and don't see where I saved the post on how to do this, and I don't recall what I did back then, but a few bucks for a switch, and maybe an hour's time made a huge improvement on mine.
I leave mine up almost all the time, except for sometimes when I am in the woods or when I am carrying a long/heavy/awkward canoe, I lower it to keep from breaking it.
If interested in this, you could probably search and find some threads on doing it.
