Does it unscrew if you need to remove when hauling on the roof rails? Owners manual doesn't say.

Doesn't look like it. However, it is flexible and will bend out of the way.

I wondered this, too. If I end up throwing kayaks up on top I don't want to snap the thing off.

OK, I looked this evening and got up on a step ladder and yes, the antenna does unscrew. Therefore, putting a kayak, or canoe, in my case, on top of the vehicle would not be a problem. Radio and XM reception will likely suffer, but only for a temoporary time.
