wi-fi legitimately in a nearby building.

The device is similar to an ipod (no phone).

I used a passive RF sniffer around the case and found a sweet spot that
has significant RF output.

What I want to experiment with is a coupling loop over the case sweet
spot going to a coax and then a directional antenna.

It would be acceptable to simply scotch tape the loop on the case.

Any suggestions on the antenna would be appreciated.

You could maybe try one of those very large metal salad bowls from
WalMart as sort of a dish reflector.. It helped me considerably in one
situation. Good luck.
