Correct Jim!

This is an old trick for those that have zero room for a 160 meter antenna. We often did this and loaded the whole shebang to be able to get on 160.

No. With the shield disconnected, the antenna is different -- if there's an effective choke at the top, it's now a long wire ending at the choke, because the shield and the center are capacity-coupled together. And if there's no choke at the top, it's a top-loaded long wire.
