twice as you'd want some slack in the cable with the gate fully
closed.

However one could use a retractable cable reel; that wouldn't have a
hanging loop.

Well a smaller hanging loop as the weight of the cable will make one
form. B-) I'd assume that out of the box it doesn't normally retract
until the "pull and release" mechanisum has been activated. That
would need disabling.
