We are dealers for Zaon, and I've asked this questions a couple times, most recently about a week ago. They do not have any plans at this time of continuing a remote antenna option.
If you do open the unit and attempt to detach the antenna, this would, of course, void any warranty.
That said, if you're successful, we'd all like to know about it. I, for one, wouldn't mind voiding my warranty on my personal unit for this benefit!
