CB base station antenna question

The long end of the insulator is supposed to be on the top. That is where the water from rain and heavy fog will run down to........
I know the current drawing of the SPT 500 Penetrator shows the short end up, but that is incorrect. Look at a drawing from the old school 500 Penetrators and it does show the long end up.

I used an adjustable hand reamer I ordered from ZORO.com.......
Just measure the OD of the vertical radial and determine the reamer that will adjust to that size. Be sure and get one that will even adjust larger so as to have plenty of room to get there.

Thanks for the help ! It doesn't make sense why they shipped it backwards.

Been a while since I was in this post but since then I have come up with a solution to my insulator problem with material I had on hand out in my garage without taking the matching system apart. Anyway it has solved my SWR problem in the rain and thought I would share it if it could help someone else if I can upload the pics. The Making pic shows what the insulator was made from and the Finish pic shows it sealed in place.
